Can the test be negative in pregnancy?

The answer to the question as to whether a test can be negative in the coming pregnancy is of interest to many women who have encountered such a situation. Let's look at it in more detail, and try to figure out in what cases after the conception a pregnancy test can show a negative result.

Can there be pregnancy with a delay and a negative test?

In order to answer this question, it is sufficient to consider the principle of the action of means for determining pregnancy.

All rapid tests that determine the onset of the gestational process are based on the determination in the urine of a woman of a hormone such as chorionic gonadotropin. It is he who appears in the body of a future mother with the onset of pregnancy and is partially excreted in the urine.

In order to determine by the most common test (strip) the fact of pregnancy, it is necessary that the concentration of this hormone reaches a certain level, i.e. in simple terms, the strip changes color only if the hormone is in a concentration that exceeds the sensitivity of the test.

However, this requires time, because The level of chorionic gonadotropin increases gradually. As a rule, only on day 12-14 from the moment of conception, its concentration reaches that necessary for the test to work.

This principle of the test works and explains the fact why it can be negative in the coming pregnancy.

In what other cases when pregnancy occurs, can the test be negative?

Talking about whether it is possible to show a negative test during pregnancy, it is also necessary to mention the rules for conducting this study. After all, if they are not observed, the likelihood of getting a negative result with the pregnancy that is taking place is also great.

So, first of all it is necessary to say that research of this kind should be conducted necessarily in the morning hours. After all, it is at this time, the concentration of the hormone is the highest, which will determine the pregnancy that has occurred.

Secondly, in order not to distort the results of the study, it is necessary to strictly follow the instructions: the test strip should be kept in the urine with a strictly specified time and do not immerse its sensitive end below the level marked on the strip.

Separately it is necessary to say that a negative result can be observed and complication of pregnancy. So, ectopic pregnancy can give a negative test, while doctors should determine whether the fetus can be preserved, or nevertheless need cleaning.
