Can I do a pregnancy test in the evening?

The onset of pregnancy for most women is quite an exciting time. That is why, with the emergence of a delay in menstrual flow, the fair sex representatives hurry to conduct the test as soon as possible. Thus often there is a question concerning, whether it is possible to do or make the test for pregnancy in the evening. Let's try to answer it.

What time of day is it better to diagnose pregnancy?

First of all, it must be said that in order for the test to work and show the correct result, a certain time must pass from the moment of conception. The thing is that almost all inexpensive express tests are based on determining the level of hCG hormone in the secreted pregnant urine. At the same time, the indicator built into this diagnostic tool only reacts to a rather high content of the hormone - 25 mm / ml.

HCG begins to be synthesized in the body of the pregnant woman practically from the first days of conception, but the concentration, as a rule, reaches the required level, indicated above, after 2-3 weeks. In other words, the use of an express pregnancy test before this date will not work.

Given this, girls are often interested in a doctor about whether it is possible to make a pregnancy test in the evening. To conduct such a study a woman can at any time of the day, but the reliability of its results still has some time dependence.

This fact is explained by the fact that immediately after awakening, as well as in the morning hours, the concentration of hCG in pregnant women in the body is greatest. Therefore, more of it is contained in the secreted urine. From this it follows that the most expedient is to conduct the test in the morning. This will give a more reliable result, sometimes even without waiting for 2 weeks from conception - with a high concentration of the hormone, the test can work and after 10 days, but the second strip will be fuzzy, sometimes hardly noticeable.

What conditions should be observed when carrying out an express pregnancy test?

As already mentioned above, if you do a pregnancy test in the evening, then there is a chance that it will show a false-negative result. However, it should be borne in mind that the information obtained depends directly not only on the time of the study, but also on compliance with the rules of express diagnostics.

So, in order for the hormone concentration in the excreted urine to not decrease, before the test the girl should reduce the amount of fluid consumed. In addition, it is very important not to take any diuretic drugs on the eve and not to eat food, which contributes to an increase in daily diuresis (everyone knows a watermelon, for example).

In addition, it is necessary to take into account the fact that the urine used for the study must be freshly collected.

Often, especially at very short gestational age, women face a situation where a pregnancy test done in the morning is positive, and if done in the evening, it is negative. Such a phenomenon can be observed for up to 2 weeks, when the concentration of hCG in the body of a woman has not yet reached the values ​​necessary for diagnosis. In this case, in the urine excreted during the night, it becomes such that the test determines the presence of the hormone.

Thus, the girl does not need to guess: whether the pregnancy test performed in the evening will show the correct result at the very beginning of the term or not, but it is better to contact the doctor with this question. In such cases, ultrasound is used to determine pregnancy, a blood test for hormones, which are an accurate method of determining not only the fact of pregnancy, but also the gestation period.
