When you need to put the test to be correct. When is the best time to take a pregnancy test for an accurate result? How to get accurate results

Women planning motherhood tend to find out about their pregnancy as early as possible. For this, special tests are recommended, which are sold in pharmacy chains. At what time is it better to apply them in order to get a real result? You can usually do a test after the first day of a missed period. But for the exact result, you need to repeat it in a week.

Understanding the principle of operation

To understand when it is better to conduct a study of urine (in the case of home tests) or blood (laboratory tests), it is necessary to understand the principle of the instrument. The task of the analysis is to detect hCG (human chorionic gonadotropin) in the test material. The body produces this hormone exclusively during pregnancy. Its minimum level appears at the moment when the fetal egg is attached to the wall of the uterus. And the maximum - by 7-12 weeks.

HCG is a hormone produced by the placenta of the fetus. Blocks the function of the ovaries to produce new eggs to avoid re-fertilization.

Most tests that can be purchased at pharmacies are able to fix hCG at a level of 25 mIU / ml. This concentration is observed on the 7-10th day from the moment of conception (the introduction of the fetal egg into the uterine mucosa). These numbers are the first component of the answer - when you need to do a urine / blood test.

However, it should be remembered that ovulation occurs according to an individual schedule. In addition, a fertilized egg can move to the uterus for 8 and 10 days.

Ovulation refers to the release of the egg, which has completed the maturation phase, from the ovary. Occurs normally two weeks before the onset of menstruation.

Features of the menstrual cycle

When deciding when it makes sense to take a pregnancy test, it is important to consider the physiological characteristics of a woman's menstrual cycle.

The menstrual cycle is a change in the female body that is periodic in nature and is aimed at creating favorable conditions for conception.

short cycle

Some women have periods less than 24 days apart. Accordingly, the timing changes when the test detects hCG in the urine.

However, the changes taking place are not pronounced, so the recommendations for when to do remain the same - 2-7 days after the delay in menstruation.

long cycle

In gynecology, cases are not uncommon when the frequency of menstruation is 32 or more days. Women with such a cycle believe that in their case it makes sense to do the test a few days earlier. However, this opinion is erroneous.

It should be remembered that with a non-standard cycle, only the first half is lengthened, which accounts for the preparation of the endometrium, that is, the surface of the uterus, for egg implantation.

While the second part, which is directly responsible for the probable onset of pregnancy, remains within the normal range - from 12 to 14 days.

cycle fluctuations

Every woman, under the influence of various factors - stress, taking certain medications, various diseases - cycle fluctuations can be observed. This has a direct impact on ovulation, that is, on the time of maturation of the egg, ready for fertilization.

For example, a woman can take a pregnancy test on the first or second day of delay (non-occurrence of menstruation) and get a negative result. Although a fertilized egg has already attached to the wall of the uterus, the level of hCG in the urine has not reached a level that can be diagnosed.

Study before delay - does it make sense?

Manufacturers of pregnancy tests in the instructions for their products do not recommend doing the study too early, that is, before the day when the next menstruation should come. It makes no sense to conduct a urine test for hCG before the third or fourth day of delay - the hormone level has not yet reached its average indicator, detected by research tools.

It should be remembered that hCG in high concentrations in early pregnancy reaches primarily in the blood. In this case, it makes sense to do laboratory research.

Time of day matters

To get a real, valid result, it is better to study urine for hormone content at a certain time of the day. Namely - in the morning, using the result of the first urination. It is morning urine that is distinguished by the maximum concentration of hCG (if any).

This requirement must be observed in the first days after the delay. After 10-15 days, the test can be performed regardless of the time of day.

In addition, there are other rules for the test:

Varieties of tests

To understand when it is optimal to do a home study of urine for hCG, knowledge about the types of tests will also help.

stripes

They are a cardboard strip impregnated with reagents that react to the hormone. It is lowered into a clean container with freshly collected urine and incubated for 20 seconds.

Tablet

An improved version of the strips - a plastic case is used to protect the reagents from external factors. Supplied complete with a pipette, which collects urine and applied to a special window.

Regardless of the type, the result is readable after five minutes.

Terms of use

Another important factor. The test should be handled in this way.

For test strips

A small amount of urine is collected in a container (clean and completely dry) made of glass. The strip is removed from the package and placed in liquid up to the level specified by the manufacturer. After 10 seconds, it is removed and laid out on a horizontal surface.

Cassette

Urine is collected with a pipette. Four drops of liquid drip into the window of the cassette. The result can be read in five minutes.

Midstream

Urine collection is not required. The test with a certain part is substituted directly under the jet so that the absorbent surface gets wet, and is closed with a cap.

If, after a second test, the result is still negative, and menstruation has not occurred, you should definitely contact a gynecologist.

Expecting a baby is an exciting and tremulous time. Many expectant mothers want a baby so much that they try to find out as early as possible if they managed to get pregnant. However, there are times when pregnancy does not occur exactly when a woman would like it. In this case, she also needs to clarify the situation and find out whether a new life has arisen in it or not.

Signs of the appearance of a small crumb in the womb of a woman in each case are individual. Even the same mother can celebrate completely different things both during pregnancy and its beginning. But there are several ways to almost unmistakably recognize the emergence of new life in the womb of a woman, even if this life has just begun. One of them is a pregnancy test. How and when is this “research” carried out, what is the reliability of its results?

How to do a pregnancy test

What is this type of diagnosis, what are the principles of "work" of tests that determine pregnancy? With the birth of a new life in the mother's womb, the production of a hormone protein, chorionic gonadotropin, begins. It is he who supports the normal development of pregnancy, stimulating the production of estrogen and progesterone. The production of the hCG hormone is carried out by the chorion tissue (shell) of the embryo and begins from the moment the latter is fixed. With the development of pregnancy, the level of hCG increases. In the early stages of waiting for crumbs, the content of the hormone doubles every 48 hours. So after how many days can a pregnancy test show a true result?

How to do a pregnancy test correctly. Terms of express diagnostics

There is hardly a woman who does not care about the question of when you can take a pregnancy test in order to get a reliable result? The onset of ovulation, during which the egg, ready to merge with the sperm, leaves the ovary, normally occurs in the middle of the woman's menstrual cycle (on the 14th day if the cycle is 28 days, on the 15th day if the cycle lasts 30 days). This date may be slightly shifted, but an indicator of a normal second phase is its duration in the range of 10-16 days. Implantation of the future crumbs occurs on the 6th - 8th day after fertilization. From this moment, the production of the “pregnancy hormone” (hCG) begins.

It is on its content in the urine that tests react, showing the presence or absence of a fetus in the mother's womb. The sensitivity of the test, indicated in the instructions for it, shows the minimum required amount of the hormone in the biomaterial (urine), which is able to recognize the "indicator" reagent. According to this criterion, you may see 10 mIU/ml, 20 mIU/ml, or 25 mIU/ml on the test. The lower the value, the more accurate the result will be and the test will recognize the conception that has occurred earlier. In most cases, the manufacturer recommends using the test no earlier than the 1st day of missed menstruation. But, if fertilization and implantation were successful, the embryo develops normally, then already at 10-12 DPO (days are counted from the moment of ovulation), the most sensitive tests (10 mIU / ml) will “stripe”. Therefore, pregnancy tests in the early stages of embryo development are the simplest and most affordable way to diagnose a “special situation”. Impatient girls and women can start express diagnostics 3 to 4 days before menstruation (data are indicated for a 28-day cycle). But it’s better to wait for the “delay” anyway - you will save yourself from unjustified hopes or hasty disappointments.

How to do a pregnancy test correctly. Rules for the use of rapid tests

So, there was a sexual intercourse without the use of contraceptives, the end of the cycle is approaching and the woman is already eager to know if conception has occurred? So it's time to go to the pharmacy and get a rapid test to detect pregnancy. When and how to take a pregnancy test? During the home analysis, it is important to follow a few simple rules:

• Do not use tests if the tightness of their packaging is in doubt or if the expiration date has passed. Such a study can hardly claim objectivity.
• Open the package immediately before testing.
• During testing, strictly follow the instructions provided by the manufacturer - lower the test to the indicated mark, observe the time frame for keeping it in the urine and subsequent evaluation of the results.
• Each test can only be used once. Then it becomes unusable.
• Use only clean containers for urine.
• The time of day for home analysis is one of the most controversial issues. If the term of the proposed pregnancy is very short (4 - 5 obstetric weeks) or testing is carried out even before the delay of menstruation, it is strongly recommended to use the morning portion of urine with the highest content of the hCG hormone. If this is not possible, do not urinate for 3-4 hours and conduct a rapid test. In cases where the diagnosis is carried out at a later date, this factor is no longer decisive and a pregnancy test is also carried out during the day.

If everything is done correctly - 90% - 95% that you will get a true result.

Reliability of pregnancy tests

A few tedious minutes have passed and 2 or 1 strip flaunts on your test. How reliable are pregnancy tests, do they show a true result? If the test was of high quality, the diagnosis was performed according to the rules, then the probability of an error is small. And yet she is.

A false negative result is possible in the following cases:

• Testing was carried out with violations.
• Analysis performed too early.
• Pregnancy is, but there are endocrine disorders.
• The level of the hormone is too low - a miscarriage may occur.

Important! If menstruation was supposed to start 1 - 2 weeks ago, and the test is still "silent", the woman should definitely visit a gynecologist. You should also determine the level of the hCG hormone in the blood - this study will give an accurate result.

A positive result in the absence of pregnancy can be in such cases:

• Violation of the ovaries.
• No more than 2 months have passed since the birth.
• There is a tumor that produces the hormone hCG (choriocarcinoma, hydatidiform mole).
• The test has expired.

If the result is doubtful in a woman, the test should be repeated after 2 days or undergo an additional examination.

Pregnancy tests: types and instructions for diagnosing

The whole variety of tests that determine the presence or absence of pregnancy is divided into several groups.

strip strips

The most popular and widespread type of express tests. Their attractiveness is due to a combination of low cost and high reliability. This test is a paper strip with a reagent applied. Evitest pregnancy tests, according to the instructions, have a sensitivity of 20 mIU / ml, however, this does not prevent the reagent from detecting the presence of the hormone in the urine even before the next menstruation (1 to 2 days before).

• Prepare a clean container.
• Collect a few milliliters of urine in it.
• Dip the test strip into the prepared biomaterial for 5-10 seconds to the indicated mark.
• Place the test on a dry horizontal surface.
• Evaluate the result after 3 - 7 minutes. (but not more than 10 minutes).

Tablet pregnancy test

If you purchased a cassette test, a urine container will come with it. Apart from this, you will also receive a special pipette for transferring drops of urine to the test.

• Collect a small amount of urine in a container.
• Take a pipette and collect a few drops of biomaterial.
• Place it in the test window and wait a few minutes (up to 10).
• You evaluate the result in another window - 1 or 2 strips.

This diagnostic method is more reliable than its predecessor, but also more expensive.

Inkjet pregnancy test

The most technically convenient test. A urine collection container is not required for diagnosis. In addition, using this type of test, you can find out about the presence of pregnancy even 5 days before the expected "delay". The negative side is the high cost.

• Take out the test and remove the cap.
• Take the test by the handle and direct its special surface for 5 seconds under the stream of urine (this part of the test is marked with an arrow).
• After a few minutes (no more than 10), evaluate the result in the test window.

Digital pregnancy test

When working with an electronic pregnancy test, follow the instructions and find out if someone has settled in your tummy. The advantage of this type of tests is not only their high sensitivity, but also the unambiguous interpretation of the meaning. A woman does not need to determine the brightness of the stripes and try to consider their number. According to, for example, the instructions for the Clearblue pregnancy test, the screen will indicate the number of weeks of pregnancy (in the case of a positive result) or a “-” icon in a circle. In tests of other brands, the inscription "pregnant" may appear.

• Open the package and take out the test.
• Dip its tip into pre-prepared urine.
• Evaluate the result.

The disadvantage of the test (in addition to the high cost) is that in a day there will be no trace of the results obtained on the screen.

Diagnosis of problems: pregnancies outside the uterus, miscarriage

Sometimes unpleasant situations lie in wait for a woman "in position" at the most unexpected moment.

Ectopic pregnancy

This pathology, unfortunately, is not a rare phenomenon. Its danger is aggravated by the fact that a woman may not be aware of the development of pregnancy outside the uterus. Seeing a second strip on a pregnancy test, a woman embraces the joy of upcoming motherhood and pleasant troubles.

Important! The production of hCG, to which pregnancy tests respond, occurs regardless of the location of the pregnancy.

That is why it is recommended to repeat the test at least 1-2 times with an interval of several days. If there is a pregnancy outside the uterus, the growth of hCG will be slower than in the case of a uterine pregnancy. To further insure herself, a woman can conduct an additional special INEXSCREEN test. It determines the content not in total hCG, but in its modified isoforms. You evaluate the result according to the given scale (below 10% - the risk of pathology is high). Thus, a woman sees whether she is at risk or if her pregnancy is not in danger.

Frozen pregnancy

In some cases, barely born life suddenly ceases to exist. How do tests behave in this case? If a woman does a “fresh” test every few days and notes a bright second strip all the time, nothing threatens her pregnancy. But suddenly the second band begins to fade. In this case, you can’t hesitate - perhaps the pregnancy can still be saved, but mandatory monitoring by a doctor is required. If the pregnancy freezes, the test line becomes paler until it disappears altogether.

It is impossible to unambiguously determine the best pregnancy test. But there are brands that have established themselves as manufacturers of reliable and reliable tests. Among them are Evitest, Clearblue, Frautest, BB test, femi test, Clear view. Regardless of the type of test you use, strict adherence to the diagnostic instructions guarantees an almost 100% result. Use high-quality tests and let them always have the desired number of bands!

Modern tests allow you to determine pregnancy as soon as possible after a "suspicious" sexual intercourse. But this cannot be done earlier than is possible in principle. And in order to correctly answer the question posed, it is necessary to understand the processes that occur after the meeting of the spermatozoon and the egg.

How does a pregnancy test work?

So, we know that after fertilization, the level of the hCG hormone in the woman’s blood begins to rise, which indicates the presence of pregnancy. Having determined this substance, the test shows us a positive result - two strips. In fact, the test reacts to the presence of the hormone gonadotropin in the urine: when the level of hCG rises, a reagent appears on the second test strip.

HCG in the body of a pregnant woman is produced immediately after the implantation of the embryo into the uterine wall, first in the blood, and a little later in the woman's urine, and usually in the urine it is in a lower concentration than in the blood. Implantation, in turn, occurs 7-10 days after ovulation. But at the same time, it must be borne in mind that the level of the hormone grows gradually, increasing daily, until it reaches a certain level, which the test is able to fix. This is the moment that sets the time frame. That is, the test is able to "detect" the presence of the hormone gonadotropin in the urine of a pregnant woman no earlier than 11-15 days after the day of the last ovulation. The lower the sensitivity threshold of the test, the earlier it will be able to determine pregnancy and the more expensive it is. Tests with a sensitivity of 10mIU / ml (usually belong to this category) are able to determine a pregnancy that has taken place a few (up to five) days before the expected period. Tests with a sensitivity of 25 mIU / ml (in the form of strip strips) determine pregnancy from the first day of delay. But these are statistics. And there are individual cases with early or late implantation. Therefore, a premature test can often be wrong.

When to do a pregnancy test with an irregular cycle?

The probability of a test error is especially high if a woman has an irregular menstrual cycle. An early test in this case may show false negative results, because the gestational age may be very short for the reactive strip to work. A pregnancy test error is more likely the earlier the test was taken.

How to do a pregnancy test?

Regardless of the regularity of the cycle and other features of the female body, the reliability of the test will be the higher, the more clearly the rules for its implementation are observed. Any violation of the instructions may cause false results.

It is believed that in the morning a pregnancy test shows the most reliable results, since the concentration of hCG in morning urine is the highest. But if the delay is already large, then by and large it is possible to conduct a test at any time of the day.

A prerequisite is the observance of the rules of sterility: no foreign substances should enter the test liquid, and therefore the hands must first be thoroughly washed and wiped dry. Also, prepare a sterile collection vessel in advance.

The test strip must be immersed in the container with urine only to the level indicated on its canvas, and always on the side where it is indicated (where the reactive substance is contained).

You should not evaluate the test result earlier than the time indicated in the instructions (usually 5 minutes) or much later. After a long period of time, the results of any test are considered invalid.

From Guest

For the first pregnancy, the test showed a positive result on the first day of the delay. On the second, only on the 5th, on the third, I didn’t show for a long time, I donated blood for hcg and found out. The children are all healthy, praise be to God

From Guest

And the test showed me two and one very weak during the first pregnancy, after menstruation and it was 5 weeks)

From Guest

And I did a test for 3 weeks of pregnancy and showed a negative result, after 10 days I donated blood for hCG and as a result, the period was 5 weeks)) And now 8 months)))

From NastenkaYour

I did a test for 7-10 days of delay, I don’t remember exactly, everything clearly showed, it was just 6 weeks from a month. and from the alleged conception of 4 weeks.

From Guest

I am now 4 days late, my husband and I really want a baby. I did the test 2 days in a row in the morning and it was negative, let's wait a little more ... maybe in 2-3 days it will show 2 cherished stripes :-)

From Guest

Delay 5 days. I did a negative test, but the delay continues, I will do another test later. And there are still symptoms

From Guest

The test showed me the correct (positive) result, only at the 6th week of pregnancy. so I don’t know who it shows on the 10th day after the PA ...

From Guest

It seems that everyone here is so happy about the pregnancy .. And now I did the test with fear .. 10 days after the pa, a negative result .. I hope I didn’t lie!

From Guest

4 days before the delay, he showed a weak 2nd strip, after another 2 days the strip was even clearer. When you are waiting for such news, tests are a good thing, I am a happy mom and the future dad is calm.

With the invention of tests for early, and most importantly, simple determination of pregnancy, women can become happy before the prescribed 6-8 weeks of an interesting situation, when the gynecologist confirms the fact of the development of a new life.

Two cherished stripes bring a lot of joyful emotions to future parents. In this article, we will talk about all the intricacies of home express pregnancy diagnostics, teach you how to do the test correctly and understand the result.

How does the test work?

All tests are based on a single mechanism - the determination of the hormone chorionic gonadotropin or hCG in the urine, the production of which begins from the moment the villi of the growing placenta enter the uterus, i.e. attachment of the embryo. Every day its quantity is growing, but at the very beginning, the growth of this hormone can only be determined by a special study of venous blood (the result will be positive 5 days earlier than the most sensitive tests begin to strip).

The sensitivity level of most rapid tests starts at 25 mUI hCG. Some manufacturers write on the packages that the test is sensitive already at 10 mUI hCG, but this is difficult to prove. As pharmacists say, this is more of a publicity stunt than the truth. Another tricky advertising ploy is the inscription that the test has the highest probability of determining pregnancy before a delay, an accuracy of 99.5-99%, etc.

If you have a regular menstrual cycle

The release of a mature egg, ready for fertilization, falls in the middle of the cycle. With a 30-day cycle, this is the 15th day, with a 28-day cycle, the 14th day. Within the next two days, fertilization can occur. After the fusion of the egg with the sperm for another 4-5 days, it “floats” to the placentation site in the uterus. Those. at about day 22 of the cycle, a blood test can already see a growing hCG. The most sensitive and high-quality tests can show 2 strips even 4 days before the expected period, when the level of hCG in the urine becomes more than 25 mUI.

Thus, you can do a highly sensitive test on the 26th day of the cycle with a 30-day cycle, and on day 24 with a 28-day cycle!

If you have an irregular menstrual cycle

To determine when ovulation occurred, you can use:

• increase in the level of basal temperature;
• appearance .

Having designated for yourself the date of approximate ovulation, 12 days are added to this number - you can already detect an increase in hCG in the blood (see). 15 days after approximate ovulation, you can do a test with high sensitivity.

What time of day should you take a pregnancy test?

As a rule, the instructions for the test strips do not recommend what time of day to test. This means that during pregnancy, the test will show 2 strips at any time.

Gynecologists also advise doing the test in the morning, using night urine. In this case, the result will be reliable, especially in early pregnancy. If you test during the day, there is a possibility of an error, since the urine is not as concentrated due to the liquid consumed during the day. The same is possible if you do the test in the evening - the content of hCG in the urine will be less. If there is a need to test during the day, then it is better to do this after a four-hour abstinence from urination, while limiting fluid intake to obtain more concentrated urine.

General rules for the correct use of pregnancy tests

• The pregnancy test must be stored under the conditions specified by the manufacturer on the package;
• The packaging with the dough must not be damaged;
• Expired tests cannot be used;
• You cannot use the same test 2 times;
• It is best to test on night urine;
• The packaging with the dough is opened immediately before use;
• Before urinating, you should wash yourself and dry yourself with a towel;
• Urination should be carried out in a clean container;
• It is very important to strictly follow the instructions: dip the test into the urine exactly to the indicated level, keep it in the urine no less and no more than the recommended time, evaluate the result only at the indicated time.

Pregnancy test - instructions for use

Pharmacies sell a variety of tests. All of them have a different cost, but they promise the same exact result. We will figure out how to use them correctly and which ones will still be the most reliable.

• The most popular and reliable are Frautest and Evitest pregnancy tests. The tests of these German manufacturers occupy an average price niche (100-140 rubles), but do not sin with false results.
• All other tests can be considered equally reliable if used correctly, especially the time to delay. The most reliable result can be obtained by testing in the first 1-3 days of a missed period.
• The cheaper the test, the cheaper the reagent that is used in it.

Strip test

Popular and inexpensive tests in the form of a paper strip coated with a layer of antibodies in hCG. The hormone contained in the urine reacts with the impregnation of the strip, and a second strip appears on the test.
Instructions for using the test. For testing, you will need a clean container in which a few milliliters of urine is collected. The test is lowered with the tip into the urine to the designated mark and held for 10 seconds. The result is evaluated within 1-10 minutes (the less hCG in the urine, the later 2 strips will appear).
Reliability - from the first day of delay.
Pros: cheap.
Cons: not convenient to use, does not show the result before the delay, may be wrong.

Reliability. Can show pregnancy even 4 days before the delay. It is considered 99% accurate when tested 2 days before the expected period.
Pros : The result cannot be misjudged, the most highly sensitive.
Cons: the result is visible only for about a day, then the inscription disappears, it will not work to leave proof of pregnancy as a keepsake. The most expensive.

Can there be a negative pregnancy test result?

HCG levels rise differently for everyone. Within 2 weeks after the delay, the test may still be negative if the woman has endocrine dysfunction or a threatened miscarriage. It will also be a false negative test if it is used too early, some women start doing tests from the day of a possible conception. Well, there is nothing harmful in this, but is it worth tormenting yourself, expecting a miracle?

Another reason is non-compliance with the rules for using the test.

False positive test result

This happens in the following cases:

• in the first 2 months after delivery;
• ovarian dysfunction;
• the development of a hormone-producing tumor (chorioncarcinoma,);
• when using an expired test.

Is the result of a test carried out during menstruation reliable?

For some women, menstruation may continue even during pregnancy. However, menstrual blood in no way affects the sensitivity of the test, so the result will be reliable. Even if a woman did a test in urine stained with spotting, if there is a proper level of hCG in her, the test will show bright 2 stripes.

Test results for ectopic pregnancy

With an ectopic pregnancy, as you know, the attachment of the fetal egg occurs outside the uterus, more often in the fallopian tube. But hCG begins to be produced in this case too. A feature is the lack of hCG growth or its slight increase.

Thus, a regular pregnancy test will show the same 2 strips. Probably, the second strip will be barely visible or more blurry than during a normal pregnancy, and the test will become positive only after the onset of a delay in menstruation.

A special INEXSCREEN test allows you to suspect an ectopic pregnancy a couple of weeks after the delay. Diagnosis is based on the detection of the level of the modified isoform in the composition of hCG, which in ectopic pregnancy is significantly lower than the prescribed 10% characteristic of normal pregnancy.

Test results for a missed pregnancy

If a clear, positive result obtained several times during the week becomes doubtful, and then the test shows only one strip at all, it is highly likely that the pregnancy is frozen. You should urgently visit a doctor.

How to decipher a dubious result?

A doubtful result occurs when there is doubt whether there is a second strip. It can be faintly visible, blurry or slightly translucent as if from the inside. The reasons:

• a low level of hCG, borderline with a minimum, at which the test becomes sensitive;
• unusable test, non-compliance with testing rules;
• a woman's great desire to see 2 stripes. Too often we wishful thinking.

What to do if the test showed a questionable result? Repeat it after a few days, and preferably 1-2 days after the delay.

Pregnancy test anti-rating

Unfortunately, it also happens that, with strict adherence to the rules for conducting express diagnostics, a pregnancy test shows a result that does not correspond to reality. Tests sin with false positive and negative results:

For the first time, every woman is destined to experience the suspicion of conception. Before visiting a gynecologist, it is easiest to check your suspicions with a simple pharmacy determinant. When is it better to do a pregnancy test - they are interested in this not only with a delay, but also after unprotected intercourse. For some, learning about the upcoming motherhood is touching and exciting, others don’t know what to do next if the test “stripes”. In any case, testing is indispensable, and it is important to know all the nuances so as not to get a false positive or false negative answer.

How does a pregnancy test work?

Conception is quite physiological for two sexually mature partners. If fertilization did not occur, there must be some reason. But the majority, having felt changes in the body after the meeting of the egg with the sperm, are surprised at a possible pregnancy, and they are in no hurry to check.

In any pharmacy there are several varieties of "striped friends of girls." But not from pharmacists, but on female forms, they often ask what to buy and when it is better to check a pregnancy test at home.

Pharmacy tests differ in a number of ways:

• verification method;
• analyzer type;
• sensitivity level;
• cost, which includes the popularity of the brand and the reputation of the manufacturer.

Chorion is the developing shell of the embryo or the future placenta that develops in the fetal egg when it is fixed in the uterus. But it happens that it is stale in the fallopian tubes, and during menstruation, you can check the pregnancy test, if in doubt.

Attention: The development of an embryo in the tubes or outside the uterus is an ectopic pregnancy dangerous for the health of a woman. In the early stages, its detection using conventional tests is problematic!

The test sensitivity threshold is their ability to respond to the minimum concentration of hCG. When you need to do a pregnancy test depends on its "competence". In the early days, it is better to buy highly sensitive rapid tests. The smaller the digital indicator, the more sensitive the determinant.

The accuracy of the analyzer does not depend on its shape, design and cost - only the reagent on a highly sensitive matrix or an impregnated paper strip in a special capsule is responsible for this. After the reaction, a symbol, a colored stripe or an inscription should appear in the result evaluation sector. The Latin letters "pregnon" (pregnant) or "non pregnon" (not pregnant) are usually used.

After how many days and when can I take a pregnancy test?

Implantation of an actively dividing egg into the uterine mucosa occurs approximately on the 7-11th day, counting from the days of ovulation. This is the release of a mature egg from the follicles in the middle of the cycle. The increase in the level of the hormone rises to the mark, starting from which the active substance of the pregnancy test applied to the strip of paper begins to react to it.

Accordingly, before checking the pregnancy test, you need to wait a while. Immediately after fertilization, nothing will be visible, although a woman can intuitively understand that this is the “X” hour! After 15 days, most tests will "stripe". But you need to wait at least 10-15 minutes for the analyzer to complete its work.

Attention: How to check a pregnancy test? Read the instructions for use or ask at the pharmacy from the one who offers it to you.

Can I take a pregnancy test in the evening?

Attention: Particularly sensitive tests can detect even a small concentration of a substance, so the time of day does not matter.

Sometimes girls (or their guys) buy 2-3 tests of different types so that if one makes a mistake, they check again. How many pregnancy tests should be done? How to find out which reagent did not lie? In any instruction, it is written about the reliability of the assessment of the analysis by 95–99%, respectively, an error is possible. There is also a false positive answer - the test "streaked", but there was no pregnancy. And what if the test showed pregnancy, and this is a false positive result? Do not rush to conclusions, check again, later go to the ultrasound clinic.

There are several reasons for wrong answers:

• the day before, a large amount of liquid was drunk (blood and urine are highly diluted);
• the gestational age is insufficient for verification;
• in the body there are traces of drugs for infertility with hormones or tumors that produce complex molecules like hCG;
• incorrectly used the test or on the wrong side (read the instructions);
• test with low sensitivity;
• pregnancy test - not morning urine, hCG level is not high enough to determine the hormone;
• expired pharmacy test (check before buying) or broken tightness;
• violation of storage conditions (pharmacy kiosk on the market, sale in the cold);
• there are remnants of biomaterial in the uterus after an abortion, spontaneous miscarriage or premature birth.

In girls who had problems with the frequency of menstruation, a false negative result may be affected by individual characteristics. With pathologies, it is even more difficult to answer what time to do a pregnancy test. The hormonal background "jumps" when paired female organs do not work synchronously. It happens that mature eggs come out of the follicles on different days, then it is difficult to indicate the exact days of ovulation.

Poor tubal patency can increase embryo travel time by several days. The mobility of the ovum in the tubes is also different. In this case, it is difficult to say how early a pregnancy test can be done, especially with an irregular cycle.

On women's forums you can read interesting remarks. For example, “I’m afraid to take a pregnancy test, suddenly it’s negative” or “I took a test this morning, but I’m afraid to look, it’s suddenly positive.” If it has already come to the suspicion of conception, feel free to go all the way, to the last point. Have an easy pregnancy, safe delivery and happy motherhood!
