We are already accustomed to using pregnancy tests at the first suspicion of this. Well and that, it is convenient, each time to the doctor you do not run. In addition, the method is quite fast and accurate. Although, about the latter you can argue, the ladies sometimes complain that the test did not show pregnancy for a long time, and then it nevertheless showed up. Let's see if the test can not determine pregnancy, and in which cases it does not show it.
Does it happen that the test does not show pregnancy?
Can a pregnancy test show it? Still as can! Especially if pregnancy is trying to determine before the delay. The fact is that hormonal changes occur gradually, and the next day after unprotected sex, pregnancy can not be determined. Usually, such a possibility appears 2 weeks after fertilization. In what other cases does the test show pregnancy?
Why does not the test show pregnancy?
It is clear, when a woman tries to determine a pregnancy too early, and the test does not determine anything. And that's why the test does not show a three-week pregnancy, what's the matter?
- The storage conditions of the test were violated, and therefore it was spoiled, or the test period expired.
- A stale urine was used for the test.
- Before testing was the taking of diuretics or a lot of liquid was used.
- There is the possibility of a problem pregnancy, for example, there is a threat of miscarriage or an ectopic pregnancy. It is for this reason that experts do not recommend fully rely on the results of rapid tests for pregnancy, and if you suspect a conception that has occurred, contact a gynecologist.
- It may happen that pregnancy has occurred and is proceeding normally, but the test still shows one strip. This happens in the presence of renal pathology, which does not allow hCG to excrete together with urine in the concentration of the test required for the reaction.
Errors in the pregnancy test
In addition to the above reasons, the reliability of the test is affected by compliance with the rules for its conduct. It happens that a woman is pregnant, but the test does not show in the following cases.
- The use of the test is not in accordance with the instructions. For example, placing the test strip under a stream of urine. And here the jet test can be placed in a jar with urine, if so it is more habitual.
- Often women pay attention to the brightness of the strip, thinking that the brighter it is, the more likely the pregnancy will be. This is not true, the brightness of the strip does not play any role, if it manifested itself within the required time - 5-7 minutes after use. The result should be evaluated only a few minutes after use, wait until the reagent dries out. In this case, after 10-15 minutes, a slightly dyed double stripe may appear, which will not mean the onset of pregnancy.
- Do not touch the reaction zone with your hands. Do not allow water or dirt to enter the test before use. Because of this test readings may be unreliable.
- It happens that the test does not show a single strip. In this case, the problem is either in the test itself or in your error when conducting it. Strips may not appear if the test did not get enough urine, the test was kept horizontally during the study.
It is worth remembering that there are also false positive test results - the woman is not pregnant, and the test shows 2 strips. Precisely because the tests are wrong and, as practice shows, quite often, it is not worthwhile to believe 100% of the test results, it is better to contact the gynecologist if there are any suspicions.
