To quickly determine pregnancy at home, the overwhelming majority of women use express tests. It would seem that the structure of such a dough itself implies only 2 possible responses, which with a 97% probability correspond to the truth. However, from time to time there is a third option: a weakly-bed pregnancy test. Is it possible to consider it negative, or still there is a chance that a woman is pregnant? And what should I do if your test turned out to be weakly positive?
Before dealing with the reasons of a weakly positive result, let's figure it out how the test is working at all. The most commonly used simple test strip. It is a small paper strip, in the right place impregnated with a special substance that reacts with a hormone of pregnant women - HCHG. The result of such a reaction becomes a change in the color of reagent. If the reaction occurred - the cherished second strip appears.
The first flat is the control, the quality of the test is monitored. That is, if the control strip did not appear, it does not matter whether the second one appeared, as the test is defective and the result is unreliable.
We remind you that the HCHG is produced by chorion that appears in the body only after the implantation of the fetal egg. From this point on, Chorion begins to develop, and the more it becomes more, the more the hormone produces. Accordingly, the number of HCHs is different at different times of pregnancy.
This is exactly the main cause of weakly positive results. When a woman acquires a test with low sensitivity, or does a test in the early lastings - on the first day of the delay, or even without waiting for it - the number of HCHs may be insufficient for full-fledged staining. It is recommended to repeat the test a few days later. The number of HCHs will increase during this time, and the test must give a positive result. Regardless of the results of the re-test it makes sense to consult a doctor for more accurate interpretation.
However, the reason may be more prosaic: non-compliance with the instructions offered to the test. Most of them offers to keep the test striped in tanks with urine a few seconds and omit only to a certain level. However, many women are confident that more - it means better. Like, I will give up a deeper, you will hold it in a little more, and the result will be more accurate. As a result, the strip is impregnated with urine more than necessary, under the influence of excess moisture and partial staining occurs.
can manifest a weakness and in the case of menopause. The fact is that during the climax in the body of a woman constantly there is a number of HCHG, the truth is very, very little. However, some particularly sensitive tests may well catch it.
All household pregnancy tests are detected in the urine of pregnancy hormone - chorionic gonadotropic human hormone (HCG). During pregnancy, HCG is first generated by a fertilized egg, and then the pocent. The fertilized egg, as a rule, is attached to the uterus mucosa for 6-8 days before menstruation delay. At this very time, a slight amount of hCG appears in the blood and the urine of the mother. Initially, the hong hong level is very low, but it quickly and predictably rises in the first weeks of pregnancy 3.
Clinically proven that all tests for pregnancy ClearBlue accuracy of pregnancy detection from the day of the expected start of menstruation is more than 99%. However, if it seems to you that you are pregnant, you want to learn as soon as possible about it for sure, and many women want to test on an earlier date. Neither are easy to use and read the results and can be used 5 days before the date of the menstruation delay.
