Many girls who live a full sexual life, carefully follow their menstrual cycle. And with a few days' delay, they rush headlong to the pharmacy to buy a pregnancy test, which, in their opinion, is the most reliable way to determine it. But sometimes it happens that such "reliable" pregnancy tests may be wrong. This is not a very pleasant moment, especially if the girl is not yet ready for the birth of the child, and trusting this method, learns about the baby already on a decent date.
To avoid such moments, it is worthwhile to know if pregnancy tests are mistaken and how accurate the result they can give. After all, as far as the pregnancy test is accurate, the further development of the current situation will depend.
Is there a test for pregnancy?
Often girls, women can not understand how it turns out that the test shows a false pregnancy or does not see it at all. After all, he was specially created to recognize a fertilized egg in the female body. But because of hormonal changes that begin only after the second week after fertilization, the accuracy of the pregnancy test may be low.
The test is not able to detect pregnancy when a woman takes diuretics that affect the release of the hormone in the urine. Also, pregnancy will go unnoticed when a woman has kidney disease or cardiovascular disease. Ectopic pregnancy can also be "not available" for a routine test.
Whether to believe in pregnancy tests is already an individual decision. But about how much a pregnancy test has a high probability of error, every woman should know.
Causes of "false testimony" of pregnancy tests
No doctor can tell exactly how much pregnancy tests are reliable. The result can only be foreseen by the woman herself, who knows her body and all her diseases well. There are several reasons why a pregnancy test can be wrong:
- the drug may be overdue or stored under the wrong conditions;
- the testing process was not carried out correctly;
- The test was done earlier than three days after the delay of menstruation;
- taking hormonal drugs with hCG in the composition;
- chorionic gonadotropin (a hormone produced after the fertilization of the egg) is produced by the tumor and shows a positive result.
For an accurate definition of pregnancy, you should not rely solely on this test. In case of suspicion of the future of motherhood, it is better to go to a polyclinic for ultrasound and blood tests, which will make it possible to determine the pregnancy within a week after fertilization.
