Are pregnancy tests wrong?

Due to the fact that science does not stand still, women can learn about their pregnancy at the earliest possible date, because already today, along with ordinary tests, there are supersensitive, and even digital tests for determining pregnancy!

But sometimes something goes wrong and the test shows a false result. What influences the fact that it turns out to be unreliable? There are several reasons for this, each of which can affect its response.

Why are pregnancy tests wrong?

The principle of the test is very simple - it shows the presence in the female body of the hormone hCG - human chorionic gonadotropin. When pregnancy comes and a fetal egg is attached to the uterus, it begins to gradually build up in the body.

But the problem lies in the fact that the release of this hormone is possible not only in pregnant women. There are other situations when he can show himself and the test will fix it. The reasons for a false pregnancy test may be as follows:

1. Menopause - at this time in the female body is produced in a certain amount of hCG, and during the delay, which is increasingly occurring with menopause, it can fix the test.
2. Some time after abortion, miscarriage or ectopic pregnancy in the body still contains this hormone. And if you now do a pregnancy test, then it will show a false positive result.
3. Some diseases that are accompanied by a violation of the hormonal background, various tumor processes can also cause an incorrect test response.
4. Hormonal failure that occurred in the body for various reasons including endocrine diseases.
5. Incorrect adherence to the instruction for the use of the test or the marriage of the manufacturer who used substandard reagents gives an error in the result.
6. Some drugs that treat hormonal problems or cause ovulation contain a sufficient amount of human chorionic gonadotropin so that a test can fix it. After taking such drugs, this hormone is excreted from the body for two weeks.

Well, we figured out if the pregnancy tests were wrong, showing a positive result. But in fact there are cases directly opposite - when the woman in position, and the result of testing is negative.

A pregnancy test will show a false result when a woman hurries, and without waiting for a delay, does the check. But the level of the hormone of pregnancy is gradually increasing and immediately after conception it is negligible to be fixed by the test.

Another reason is incorrect manipulation. A woman, nervous, hurry to learn the result, and does not attach importance to such details as the purity of the container for urine, the time of its collection (morning or not). In addition, there is a difference between a jet and an ordinary test. The first one must be placed under the stream of urine, and the second one should be lowered into the liquid for a while. Such seemingly insignificant details can lead to the fact that the pregnancy test will have a false negative result.
