Minimum gestational age detected by the test

So, have you missed your period or started feeling sick in the morning? Or maybe you have a craving for something salty or even exotic?

Very often, all these newly appeared signs indicate that the woman is pregnant, but none of these signs gives an accurate result. That is why modern busy women go to the pharmacy to buy a pregnancy test.

All of them are based on approximately the same principle - searching for hCG, that is, human chorionic gonadotropin, in the urine. It is this substance that can manifest itself only in pregnant women, remaining in her body throughout the entire period until childbirth.

hCG

Special tests contain a special chemical reagent that, when interacting with hCG, can show the result. At the moment, the minimum period of pregnancy that is subject to pharmacy tests is 14 days. However, these results are very inaccurate, so it is better to do this analysis again after a couple of days.

There is a popular belief that the test can show results in a short time - almost the next day after fertilization.

Such results are still fantastic, so it is better to bide your time and wait for the moment when the test can absolutely correctly answer the desired question.

Pregnancy test - from what date does it show accurately?

Many people want to determine the presence of pregnancy in the very early stages. However, such measures lead to the fact that at such early stages the presence of hCG is so small that even the most sensitive test is not able to detect them. That is why it is very important to determine the period within which the test will help to obtain the most correct result.

Every woman has a standard cycle between periods, which usually lasts about 27-28 days. When the cell leaves the follicle on day 14, the woman becomes able to conceive.

It usually takes about 3-5 more days for the cell to be fertilized immediately after the chromosomes have been fused for the pregnancy to begin to appear. After this, human chorionic gonadotropin begins to be produced, which approximately doubles every day.

Cycle

When it reaches a level of more than 30, tests are able to determine pregnancy with almost absolute accuracy. Of course, it is advisable to do it approximately on the 6-7th day of the delay, using morning urine, then the result will be more correct.

How to carry out the procedure?

To obtain a reliable positive result in the early stages of pregnancy, the following conditions must be met:

  • Wait for the delay . The more days have passed since the expected start of menstruation, the more likely it is that clear two lines will appear on the test.
  • Conduct research in the morning. After waking up, you need to do a test using the first portion of urine. It contains the maximum amount of the hCG hormone. The likelihood of a positive result occurring at this time of day is highest. The exception is sensitive inkjet and electronic tests, which can be performed at any time.
  • Follow instructions. Failure to comply with testing rules may lead to unreliable data obtained. Instructions for using the test are always present inside the package.
  • Consider the quality of the test. The device must be purchased from a pharmacy and have a valid expiration date. It is important to purchase trusted manufacturers.

The appearance of two lines on the test does not always indicate pregnancy. A false positive result may occur in women who have recently had an abortion or miscarriage. Also, a positive reaction can be observed after surgery, the use of hormonal drugs, due to the presence of cysts or uterine fibroids, etc.

How many days after intercourse does the test show results?

It is very important for any woman to know how quickly she can find out whether she has conceived or not. However, as mentioned earlier, hCG increases gradually and you need to wait until a sufficient amount of it accumulates in the blood.

However, if a woman knows the exact day of sexual intercourse, then it is possible to calculate the approximate time when the test will accurately determine what the result is. So, how long after intercourse does a test show pregnancy? The standard is two weeks after sex.

However, during this period a false positive result is also possible, so it is better to wait a few more days.

It is best to focus here on menstrual delay, but if yours is quite irregular, then count about 19 days from when you had unprotected sex and take a test. It is after 2.5 - 3 weeks that the result will be accurate.

On what day of delay should you take the test?

One of the important dates for determining when to take a pregnancy test is menstrual delay. Typically, such a day is written in the instructions for the test, so be sure to read it before use.

If you chose strip strips or tablet tests, then it makes no sense to do the test before the second day of the delay has arrived. At their core, there are tests that can determine pregnancy even before the delay occurs, but these days are the most suitable for performing it.

For more accurate results, you should wait until 5-6 days of delay, when there is a sufficient amount of hCG in the blood and urine, which is produced in each woman at different rates.

Change in hCG level

HCG is human chorionic gonadotropin (hormone). Immediately after the transfer of a fertilized egg to the uterine wall, it is formed in the body of the expectant mother. The body needs the hormone until the placenta forms. In the initial stages, it stimulates the production of other important hormones.

Determining the level of hCG is one of the most detailed tests in the twelfth week. For this purpose, urine tests are performed. A pregnancy test may be used.

Hormonal levels change as pregnancy progresses. Until the 12th week it grows (doubling every 48 hours), and then there is a sharp decrease.

The information is reflected in the table below.

Gestational ageHCG level
0 — 15 — 25
1 — 225 — 156
2 — 3101 — 4870
3 — 41110 — 31500
4 — 52560 — 82300
5 — 623100 — 151000
6 — 727300 — 233000
7 — 1120900 — 291000
11 — 156140 — 103000

At what stage of ectopic pregnancy will the test show the result?

One of the most difficult trials that befalls a woman is an ectopic pregnancy. Many people are afraid of her, and there really is every reason for this. But how does it affect what results the tests show?

Very often, it does not affect the result in any way, since as the fetus grows, the hCG hormone is still released in the blood and urine, regardless of where the baby grows. However, there are several features:

  • very often hCG begins to be produced with a delay, so the result can be very weak. The second stripe in such a situation is usually pale and even after some time does not become bright;
  • very often the test result can fluctuate: be either positive or negative;
  • The menstrual cycle continues and there is no delay, so it is very difficult to determine the right time.

Tests can be done for women with an ectopic pregnancy, but they may not give accurate results. Here it is best to use an ultrasound.

Review of the best tests to determine pregnancy in the early stages

At the moment, there are a huge variety of pregnancy tests in pharmacies. However, to determine the timing in the early stages, use not strip strips, but inkjet tests, which are the most sensitive. However, professionals do not particularly distinguish between them.

What tests best show early pregnancy:

  1. MediSmart TOP Early Pregnancy Test - this jet test is considered one of the most sensitive and at the same time accurate in the whole world. It can be used a few days before menstruation using urine from a night's sleep. To carry it out, you need to remove the cap and hold it under stream of urine for 10 seconds. After this, immediately close the cap and wait 5 minutes. If 2 stripes appear, then you are pregnant. Based on the color saturation of the strip, you can determine the period: pale pink 1-2 weeks, pink 2-3, and red more than 3 weeks.
  2. The Clearblue test system is digital and therefore very easy to use. The result here will be displayed on the screen, and the exact result can be obtained already in the first couple of days of the delay. Before this, the accuracy percentage is only 55. This test should also be placed under a stream of urine and wait 3 minutes. The result will be given as a plus or minus, after which you will also be told your gestational age. However, such a test takes into account only the embryonic period, so it is worth adding 2 weeks to know the obstetric period.

As you can see, pregnancy tests can give a fairly accurate result, the main thing is to know when to do them, and not run to the pharmacy the next day after the act.

Methods for determining pregnancy

The question of how to determine pregnancy in the early stages is the most common among women planning to conceive. Today there are many methods for establishing the fact of successful conception. Some of them require special reagents and laboratory conditions, others can be carried out at home. It is worth noting that laboratory tests are highly accurate and help determine gestation from the first days of its onset. Conventionally, all existing identification methods can be divided into:

  • hardware: ultrasound, Doppler, CTG;
  • laboratory – blood and urine tests;
  • folk (according to the signs and well-being of a woman).

Methods for determining pregnancy in medicine

The most popular and accessible means of diagnosing pregnancy is a pharmacy test. Its mechanism of action is based on establishing the concentration of hCG in biological fluids of the body (in urine). The technique is effective only with the onset of delayed menstruation, when the hormone concentration reaches diagnostic values. Pregnancy can be diagnosed using the following methods:

  1. Laboratory research.
    A blood test for the concentration of hCG levels helps to establish the fact of pregnancy already on the 10th day from the moment of conception.
  2. Ultrasound is the most informative method.
    With its help, you can not only determine pregnancy, but also determine its duration.
