Pregnancy test 25 mme ml when. How and when is the best time to take a pregnancy test. Are the results reliable if tested during menstruation?

Choosing the best pregnancy test is quite problematic, since each has its own advantages and disadvantages: some are too high price, others are inconvenient to use, others do not always show accurate information. How to choose the best test? What should you pay attention to when purchasing and how to use it correctly so as not to get a false result?

Tests can be found not only in pharmacies; they are often sold in supermarkets and small shops. Analyzers for early detection of pregnancy are available in a wide range of prices depending on the manufacturer and type.

The effect of a pregnancy test is based on the mechanism of interaction of a special substance with human chorionic gonadotropin (). This hormone begins to be intensively produced in the female body a short time after conception. It is produced by the embryo starting from the eighth day after the fusion of male and female gametes or the day after the fertilized egg in the uterine cavity.

The tests are based on the immunochromatography method. Its peculiarity lies in the fact that the substance that needs to be detected combines with antibodies to it, resulting in a positive reaction. When determining pregnancy, this substance is hCG.

An active substance with a coloring agent is applied to a strip of dough. When urine enters, hCG gradually moves, and when it reaches the “positive reaction” strip, the dye is released and shows the result. If there is no human chorionic gonadotropin in the urine, then staining of the second line will not occur.

When a hormone appears in the urine, its concentration doubles every day. On days 7-10 after the fusion of the egg and sperm, the amount of human chorionic gonadotropin reaches 25 mIU/ml, and its peak concentration can be observed between the eighth and eleventh weeks of pregnancy.

It is difficult to answer unequivocally which pregnancy test is better, since there are a large number of various types. Tests with high sensitivity to hCG can detect pregnancy after a week.

Review of the best foreign tests

There are a large number of diagnostic strips that can be called the best early pregnancy tests. All of them are divided into several groups, depending on the degree of sensitivity and material.

Strip test

The most common and affordable pregnancy tests used in the early stages.

Frautest Express – a paper test strip, packed in an individual bag and a box with instructions. The sensitivity is 15 mIU/ml. The advantages of the test include low cost, ease of use, and quick results (after 3-5 minutes).

According to the manufacturer, the reliability of the results reaches 99% even when used 1-2 days before the expected start date of menstruation. However, user reviews do not always agree with this statement.

One of the negative aspects is the need to use containers for collecting urine.

How to use the test strip:

Read the instructions.
Fill the container with urine.
Open the individual pouch and remove the test strip.
Lower the test into the glass of urine to the indicated level and wait 10 seconds.
Place on a horizontal surface.
Evaluate the results after 5 minutes, but no later than 10.

Frautest Double Control has similar characteristics, the only difference is that the box contains two test strips to confirm the result.

Evitest One also applies to strip tests. The package contains one test strip. The sensitivity of hCG is 20 mIU/ml, which allows you to determine the exact result from the first day.

Advantages:

affordable price;
clear instructions for use;
ease of use;
reliability of results 98%;
It is sold not only in pharmacies, but also in stores, so purchasing it will not be difficult.

Among the disadvantages, it can be noted that the price of these products is slightly higher than for similar test strips from other manufacturers. Also, the results of the test are not always easy to decipher due to the fact that.

Evitest is easy to use:

After removing from the package, lower the strip into the container with urine to the level marked on the test for 5 seconds.
Evaluate the results in 3-5 minutes. The appearance of two red marks indicates the presence of pregnancy.
If in doubt, a repeat test the next morning is recommended.

Evitest Plus contains 2 strip tests in a cardboard package and is intended for reliable determination of pregnancy.

Tablet

Frautest Expert is rightfully considered one of the best pregnancy tests. The analyzer is a cassette with a sensitive strip enclosed inside, complete with a pipette for applying urine. The test is ultrasensitive (15 mIU/ml), so it can be performed a couple of days before menstruation. Accuracy - up to 99%.

Instructions for use:

Collect your morning urine in a container.
Remove the test plate and the supplied pipette from the package.
Take a couple of drops and place them in a special window on the cassette.
Place the test on a flat surface.
Evaluate the data obtained after 5 minutes.

Among the positive characteristics, one should note the high accuracy of determining pregnancy, use even with a small amount of urine, and detection of pregnancy before the onset of delay.

The disadvantages include some difficulty in use, as well as a higher price compared to test strips.

Evitest Proof – tablet test for detecting pregnancy with a sensitivity of 20 mIU/ml and an accuracy of up to 99%. Its main advantage is the convenient design of the cassette, in which the test window is located in a recess, which eliminates the possibility of accidental contamination with fingers and changes in diagnostic results. In addition, the tablet allows urine to be distributed more evenly, which affects the reliability of the results.

On the negative side: to carry out the test, you need to be in a comfortable environment, preferably at home, since you need to very accurately place a couple of drops of urine into the hole intended for this.

Instructions for use are the same for all tests of this type.

Jet

According to doctors, they give the most accurate results. To get an answer whether you are pregnant or not, it is better to do the diagnosis in the morning, when the concentration of human chorionic gonadotropin in the urine is highest.

Using stream tests is simple - during urination, you need to place the analyzer under a stream of urine, wait a little, and after 3-5 minutes you will receive an answer to the main question.

Frautest Comfort – an ultrasensitive test that shows results at a hCG concentration in urine of 15 mIU/ml. The special design allows the diagnostic device to be used without any difficulties and in any place where there is a toilet.

Advantages:

no need to collect urine;
convenient dough structure;
The tightly fixed cap eliminates the possibility of violating the test results.

Flaws:

high price;
There is a small risk of getting your hands dirty when urinating.

Frautest Exclusive has similar characteristics to the previous product. The only exception is the more modern appearance case, made in pink.

Evitest Perfect It is a plastic case with a protective cover, inside of which there is a diagnostic strip. The manufacturer indicates a sensitivity of 20 mIU/ml.

Premium Diagnostics - a highly sensitive jet-type pregnancy test, which gives results at a hCG concentration of 10 mIU/ml in the urine. According to the manufacturer, this jet test allows you to establish the fact of pregnancy on the seventh day after conception.

pros:

ease of diagnostics;
high accuracy of results (99%);
the test can be performed at any time of the day;
Can be used in a doctor's office to confirm examination results.

There were no clearly identified negative characteristics of the test.

Electronic

Today, analyzers are the best tests for determining pregnancy.

The Digital device is one of the modern and most precise methods for rapid diagnosis of pregnancy at home. It has supersensitivity - 10mIU/ml.

Advantages:

accuracy of results exceeds 99%;
in addition to the presence of a pregnancy mark, the device displays the expected period on the screen (1-2 weeks, from 2 to 3 weeks and over 3 weeks);
When the fact of fertilization is established, the accuracy of detecting the period is 92%.

The disadvantage is the high price, exceeding the cost of all previously indicated samples.

Instructions for using the electronic test:

Place the diagnostic section of the test under a stream of urine, being careful not to get urine on the rest of the product.
Attach the cap and wait for the test results to appear on the screen.
The test can also be used by immersion in a container of collected urine.
To get accurate results a few days before the expected day of menstruation, it is better to do the test in the morning.

Many women rate Clearblue Digital as the best pregnancy test.

Reservoir

The rarest type of pregnancy test, which is a measuring cup with a built-in test strip on its surface to determine the presence of human chorionic gonadotropin.

Such tests are difficult to find in pharmacies; they are very expensive, so their demand is very low.

Review of the best Russian-made tests

The domestic pharmaceutical industry is also engaged in the production of means for express determination of fertilization. However, today there are only a few analyzers, mainly represented by test strips. We will try to identify the best Russian-made pregnancy test.

Strip test

Russian test strips for determining pregnancy:

Insure – pregnancy test with a sensitivity of 12.5 mIU/ml. Its advantages include high accuracy of results, starting from the expected start date of “critical” days, simple and understandable instructions for use, affordable price. There are no obvious shortcomings, this is one of the best pregnancy tests.
"Rest assured" is a popular test among Russian women that shows accurate results. Strip strips are sensitive to hCG in urine, starting from a concentration of 25 mIU/ml. The advantage is the low cost. No negative aspects have been identified.
"HCG-IHA-VERA" . Susceptibility of these strips begins at a concentration of 20 mIU/ml. The product has a very low price, which is why it is in demand, but customer reviews often indicate that the diagnosis was not accurate, and even testing of morning urine often showed.

Tablet

"BIOCARD hCG" - a test in the form of a cassette with two windows: in one you need to place 3-4 drops of urine using a pipette, and in the other, the result will appear after 5 minutes. The sensitivity is 20 mIU/ml. According to the recommendations specified in the instructions, it is good to do the diagnosis in the morning, immediately after waking up. In this case, the day before you should not abuse liquids and take medications, so as not to get a false result.

Advantages:

high degree of accuracy – up to 99%;
reasonable cost in comparison with imported analogues;
The test is effective from the first day of missed menstruation.

Flaws:

long waiting time for a reaction – more than 5 minutes;
the second stripe is not always clearly colored;
For reliable indicators, it is recommended to test with morning urine.

Using the analyzer is simple: place the test under stream of urine, then close the cap and wait about 5 minutes.

What to look for when choosing a test

According to the manufacturers, the lower the figure indicated in the instructions, reflecting the concentration of human chorionic gonadotropin in urine, the higher the accuracy and sensitivity of the analyzer. However, this is not an entirely true statement, since hCG is detected only 7-8 days after fertilization with a concentration of 25 mIU/ml, and this value doubles every day.

On minimum period It is better to take a pregnancy test in the morning; the hormone content in the urine is maximum at this time. Following this simple rule allows you to detect a successful conception already from the first days of the delay.

The pharmaceutical industry, both foreign and domestic, produces a large number of devices for express diagnostics of fertilization, so it is difficult to definitively answer which pregnancy test is better. According to statistics, inkjet and electronic tests show the most accurate results.

Useful video about the best pregnancy tests

Replies

Today, pregnancy tests are available in a wide range. There are several types of tests:

Strip tests: special strips that need to be dipped into a container with urine, sensitivity threshold - 10-25 mIU/ml ( amount of hCG in 1 ml of urine).
Tablet: a plastic case in which there is a window with a substance sensitive to hCG. You need to add a few drops of urine into this window. Sensitivity threshold 10-25 mIU/ml.
Jet: do not require collecting urine into a separate container - a pregnancy test can be performed directly during urination, placing the analyzer under the stream. Sensitivity threshold from 10mIU/ml.
Electronic (digital): they have several varieties and can be intended for repeated use or determining the duration of pregnancy, etc.

Each type of test has its own advantages and disadvantages. Now we’ll try to figure out which pregnancy tests are the best.

Frautest Express Ultra sensitive

Photo: frautest.ru

The cost of a package with one strip test is about 85 rubles.

The sensitivity of the Frautest express pregnancy test starts at 15 mMKU/ml and, according to the manufacturer, it can be used without waiting for a missed period, and even 2 days before the date when (possibly) the countdown from the “missed” first day of menstruation begins. The test results are determined 3-5 minutes after you remove the strip from the urine container.

Flaws. The need to look for a container for urine, fill it, hold a strip test in it for 10 seconds and then think about how to dispose of the filled “container” is not entirely convenient outside the home.

Advantages This pregnancy test is easy to use and highly reliable (up to 99%). Well, let’s not pretend that cost doesn’t matter. The affordable price is a huge plus.

conclusions. One of the best pregnancy tests. A well-deserved rating of 10 out of 10.

Reviews.“I have already bought a test from this company twice, or rather, this time my husband bought it, and it did not disappoint again. My opinion is that there is no need to buy expensive tests, even if they tend to show the number of weeks. This pregnancy test is reliable, It is sold in all pharmacies, it is convenient to use and attractive in price."

Frautest Planning

Photo: frautest.ru

The cost of a set of 5 strip tests for determining ovulation, 2 for pregnancy and 7 disposable containers for collecting urine is about 380 rubles.

Another “nominee” from the Hungarian company Human takes a leading position in the ranking of the best pregnancy tests. Frautest Planning is excellent remedy for women who are planning a pregnancy and want to verify the fact of its occurrence (or the need to continue trying) without leaving the cash register.

The well-thought-out configuration of this strip kit allows you to cover the entire period from the probable start date of ovulation and “catch” the moment necessary for conception until pregnancy is determined (you can start checking 2 days before the expected day of delay). An added bonus is the disposable urine collection containers, which are easy to dispose of and allow you to take the test under any conditions.

Flaws. The only drawback is high price. But this is only at first glance: the same set, but “scattered” into separate packages, will cost about 70 rubles more.

conclusions. Best test for pregnancy for those who care not only about a healthy lifestyle from the first days of pregnancy, but also understand the importance of planning for this fateful moment. Well-deserved ten!

Reviews. « I made big mistakes several times when I used ovulation tests and pregnancy tests from different manufacturers. The consequences were, to put it mildly, painful for my nervous system. 3 months after using Frautest for planning, I finally got on the right “schedule”. The result - in the fourth month, a pregnancy test confirmed that you can be happy. I highly recommend it - it’s expensive, but it’s reliable and doesn’t confuse you with false results.”

Clearblue Digital

Photo: www.thedrugstorelimited.com

The cost of a package with 1 digital test is about 480 rubles.

Advantages. If we take the percentage of accuracy with which the test determines the presence of pregnancy as a unit of quality, then Clearblue Digital sets the bar incredibly high: above 99%. One hundred percent accuracy is just around the corner, and this test is one of the most reliable today. But that's not all. In addition to the mark indicating the presence/absence of pregnancy (“+” - yes, “-” - no), a number will appear in the window indicating the duration of pregnancy in weeks. The format of the indicators corresponds to the range of 1-2 weeks, 2-3 weeks and more than three (the image “3+” will appear on the display). If conception does occur, then the accuracy of determining the due date, according to the manufacturer and research results, is 92%. Impressive, isn't it?

If your period is delayed, the test can be used from the very first day of its expected start. But if “you can’t bear to wait,” and your body persistently hints about your interesting situation in other ways (for example, by the desire to eat persimmons, having previously smeared them with toothpaste), then the test can be performed 4 days before the date of the likely delay.

Flaws. Not everyone will consider determining the gestational age a necessary function. Still have to visit the doctor, ultrasonography and blood tests - together, all this will establish the deadline even without a test. But let's remember the “surprises” of pregnancy, which can calmly coexist with regular periods. In this case, it is often important for a woman to understand how far along she is, and whether she has enough time to contact an antenatal clinic and register. A classic example is a long business trip or business trip, when the dilemma of “dropping everything and going home versus still having time, you can wait” ruins all plans. So, whether this is a disadvantage or not is up to you to decide.

conclusions. Considering that not everyone is interested in setting an exact date without visiting a doctor, but this function makes the price “bite”, the rating is 9 out of 10.

Reviews. “I felt something was wrong as soon as I arrived on vacation. With my floating and irregular monthly cycle, I assumed that pregnancy might no longer be possible. early. The KLeablu test showed that I have been pregnant for more than three weeks. I limited myself to rides and other active entertainment, and when I returned a week later and went to the doctor, the period turned out to be already 6 weeks. The test didn’t disappoint.”

Evitest Proof

Photo: s5.stc.all.kpcdn.net

The cost of a package with one tablet test is about 190 rubles.

Advantages. The main advantage rather relates to the design of the test: the tablet model allows urine to be more evenly distributed over the surface of the substrate with the reagent, which, accordingly, increases the reliability of the results. The second plus is the “purity” of the results. It is impossible to touch the reagent, which is located in the recess of the window, with your fingers, even by accident, so possible contamination of the sample (not a fantastic event, by the way) is simply excluded.

Flaws. You may feel like a professor in a chemistry laboratory who carefully and carefully introduces a special substance (urine) onto the surface of the test object (test) so that there is no explosion. Nothing will really explode, except maybe your patience if you're nervous and your hands are shaking. Therefore, it is better to conduct “experiments” at home, where you can relax (or at least pretend) and finish what you started.

conclusions. One of the best tablet pregnancy tests when it comes to the accuracy of the results. And this is the main reason why you decided to buy it, isn’t it? This means that giving it a rating of 10 out of 10 would be correct and fair.

Reviews. « I was treated for infertility for a long time and used only this test. I don’t even know why - I was superstitiously afraid to change it for another. And 2 years later he showed a positive result for the first time! Positive and correct».

Premium Diagnostics

Photo: www.premiumdiagnostics.ru

The cost of a package with one jet test is about 120 rubles.

Advantages. A quick and accurate result (up to 99% - if the test is carried out after the first day of the delay), for which there is no need to collect urine - an excellent alternative to the “strip” traditions. At the same time, a control window is provided in the cassette, which represents the test. Regardless of whether the result is positive or not - if a red line appears in the control window - the test was carried out correctly.

Flaws. The ability to perform the test without the need to collect urine will be a very useful feature of the test for some, but inconvenient for others. But, as they say, you won’t be nice to everyone - let’s not count this as a disadvantage.

conclusions. An excellent pregnancy test that will fulfill its purpose both in a cozy home environment and in “camping” conditions, when there is no time or opportunity to look for and fill a urine container. In our opinion, 10 points is a well-deserved rating.

With the invention of tests for early, and most importantly simple, determination of pregnancy, women can become happy before the required 6-8 weeks of pregnancy, 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 human chorionic gonadotropin or hCG in the urine, the production of which begins from the moment the villi of the growing placenta penetrate the uterus, i.e. attachment of the embryo. Its amount is growing every day, 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 show signs).

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

If you have a regular menstrual cycle

The release of a mature egg, ready for fertilization, occurs in the middle of the cycle. With a 30-day cycle this is the 15th day, with a 28-day cycle it is the 14th day. Over the next two days, fertilization can occur. After the fusion of the egg with the sperm, it “swims” for another 4-5 days to the placentation site in the uterus. Those. Around day 22 of the cycle, a blood test can already show a rising hCG. The most sensitive and high-quality tests can show 2 stripes 4 days before the expected menstruation, when hCG level there will be more than 25 mUI in the urine.

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

If you have an irregular menstrual cycle

You can determine when ovulation occurred using:

increasing the level of basal temperature;
appearance .

Having set the date of approximate ovulation for yourself, add 12 days 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 test strips do not recommend what time of day to test. This means that during pregnancy the test will show 2 lines at any time.

Gynecologists advise doing the test in the morning using night urine. In this case, the result will be reliable, especially in the early stages of pregnancy. If you test during the day, there is a possibility of error, since the urine is not as concentrated due to the fluid consumed during the day. The same thing is possible if you do the test in the evening - the hCG content in the urine will be lower. If there is a need to test during the day, it is better to do this after abstaining from urination for four hours, 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 packaging;
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 overnight urine;
The package with the test is opened immediately before use;
Before urinating, you should wash yourself and dry yourself with a towel;
Urination should be done in a clean container;
It is very important to strictly follow the instructions: lower the test into urine exactly to the indicated level, keep it in 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 many test options. They all have different prices, but equally promise accurate results. Let's figure out how to use them correctly and which ones will be the most reliable.

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

Strip test

Popular and inexpensive tests in the form paper strip with a layer of antibodies in hCG applied to it. 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 several milliliters of urine are collected. The test tip is lowered into the urine to the designated mark and held for 10 seconds. The result is assessed within 1-10 minutes (the less hCG in the urine, the later the 2nd strip will appear).
Reliability – from the first day of delay.
Pro: cheap.
Disadvantages: not convenient to use, does not show results before a delay, can make mistakes.

Can a test result be negative during pregnancy?

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 is at risk of miscarriage. The test will also be false negative if it is used too early; some women begin taking tests from the day of possible conception. Well, there is nothing harmful in this, but is it worth tormenting yourself while waiting for 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;
development of a hormone-producing tumor (chorionic carcinoma);
when using the test with expired suitability.

Is the test result taken during menstruation reliable?

Some women may continue to have periods during pregnancy. However, menstrual blood does not in any way affect the sensitivity of the test, so the result will be reliable. Even if the woman did the test in urine colored bloody discharge, if there is a proper level of hCG in it, the test will show 2 bright stripes.

Test results for ectopic pregnancy

At ectopic pregnancy, as is known, attachment ovum occurs outside the uterus, most often in the fallopian tube. But hCG begins to be produced in this case too. A peculiarity is the absence of an increase in hCG or its slight increase.

Thus, a regular pregnancy test will show the same 2 lines. It is likely that the second stripe will be barely visible or more blurred than with normal pregnancy, yes and positive test It will only happen after 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 identifying the level of the modified isoform in the composition of hCG, which in ectopic pregnancy is significantly lower than the required 10% characteristic of normal pregnancy.

Test results for frozen pregnancy

If a clear positive result obtained several times within a week becomes doubtful, and then the test shows only one line, there is a high probability that the pregnancy is frozen. You should urgently visit a doctor.

How to decipher a questionable result?

A questionable result occurs when there is doubt whether there is a second stripe. It may be faintly visible, blurry, or slightly visible, as if from within. Causes:

low level of hCG, borderline minimal, at which the test becomes sensitive;
unusable test, non-compliance with testing rules;
A woman’s great desire to see 2 stripes. Very often we wishful thinking.

What to do if the test shows a questionable result? Repeat it after a few days, or better yet, 1-2 days after the delay.

Anti-rating of pregnancy tests

Unfortunately, it also happens that if the rules for express diagnostics are strictly followed, a pregnancy test shows a result that is not true. The following tests cause false positive and negative results:


Faith	rest assured	Bee-Sure	Bebicek	Mon Ami

Pregnancy tests sold in any pharmacy for home use They differ not only in cost, but also in the method of taking the test itself, and most importantly, in the level of sensitivity.

Home pregnancy tests determine the result based on the level of the hormone hCG (human chorionic gonadotropin, produced only during pregnancy) in the urine. This hormone is produced by the chorion (the membrane of the embryo) after it is fixed in the uterine cavity. From this moment, the concentration of hCG in the woman’s urine begins to increase, and the quality and sensitivity of the test determines when you can get an accurate answer whether pregnancy has occurred.

The sensitivity of pregnancy tests is marked with numbers 10, 20, 25, 30, which corresponds to the concentration of hCG in urine in mIU/ml (international units per ml) that they are able to detect. The lower the number, the higher the sensitivity of the test and its accuracy.

Before missed period

The most sensitive and most expensive tests recognize the appearance of a baby even before the expected start date of menstruation - already seven to ten days from the moment of expected conception. Carefully read the information on the package; the sensitivity of such a test should be 10 mIU/ml. As a rule, inkjet tests have the desired characteristics.

A blood test for hCG is another way to find out about early pregnancy. On the 12th day after the date of expected conception (that is, with a long cycle even before the delay), based on the results of this analysis, it will already be possible to say whether pregnancy has occurred in this cycle or not, and to accurately name the due date. The presence of hCG in the blood can be determined earlier - already on the seventh day after conception, however, the results may be inaccurate and you will need to take the blood again a week later to confirm them.

When choosing the time to take a pregnancy test, keep in mind that the hCG blood test is best taken in the morning on an empty stomach. If you come in the afternoon, be prepared to not eat for four to six hours before your blood is drawn. It is also recommended to avoid physical activity before the procedure. If you are taking any hormonal medications, discuss this with your doctor before donating blood.

First or third day of delay

Most home tests have a sensitivity of 20–25 mIU/ml and provide accurate results from the first day of a missed period. It is useless to use such a pregnancy test when it is too early to do it - the answer will be negative, even if pregnancy has actually occurred.

Fourth to seventh day of delay

A definite answer can be obtained after a significant delay in menstruation. At this time, any test, if it is working properly, will show an accurate result. It is worth considering that with the help of a home test you can only determine the presence or absence of pregnancy, and its exact duration can only be determined by taking a blood test for hCG.

What time to take a pregnancy test

It is better to take a home pregnancy test in the morning, when the concentration of the hCG hormone in the urine is maximum.

If it is more convenient for you to take a pregnancy test in the evening, be sure to choose the most sensitive jet test, for which exact time carrying out is not of serious importance.

Pregnancy tests for home use sold in any pharmacy differ not only in cost, but also in the method of taking the test itself, and most importantly, in the level of sensitivity.

If it is more convenient for you to take a pregnancy test in the evening, be sure to choose the most sensitive jet test, for which the exact time of the test is not of serious importance.
