Weak strip on the pregnancy test

Regardless of the price and quality of pregnancy tests, they all work on the same principle: a positive or negative result is determined by the reaction of the reagent to the hormone gonadotropin, which appears if pregnancy has taken place. High-quality tests react to this hormone even at the level of 25 mIU / ml. To this level, the hormone chorionic gonadotropin increases on the first day of the delay. Then every two days its level doubles and reaches a peak at the eighth or eleventh week of pregnancy.

Doubtful pregnancy test

Each test has two zones: one of them is a test zone, the other is a test zone. The reaction of the control zone occurs on contact with the urine and indicates the quality of the test, and the reaction of the test zone determines pregnancy. It is covered with a reagent sensitive to the gonadotropin. If in the test zone on the pregnancy test the band appears very pale, then it should not be regarded as a 100% positive result.

In the event that a weak strip appears after the recommended test time, it is non-informative data. Also, if as a result of the test, a second strip of gray appeared on it, then this is more like a ghost on a pregnancy test. This may be due to the drying out of the unreacted reagent or, if the urine test is overtaken in the urine, which will provoke the ingestion of excessive amounts of liquid.

Causes of mild pregnancy test

First of all, you need to know that the test reacts not to the pregnancy itself but to the increase of the gonadotropin hormone. An increase in its level in the body can provoke the development of such a pathological process, as the formation of cysts or tumors. Also, this hormone can have an elevated level for some time after miscarriage, removal of an ectopic pregnancy or abortion .

Increase the level of gonadotropin can some hormonal drugs, which he includes (Gonakor, Pregril, Profazi, Gonadotropin chorionic, Horagon).

Weakly positive pregnancy tests are much less common than false-negative ones. In such cases, the test does not determine pregnancy when it is actually available. A pale pregnancy test is unlikely to be a sign of pregnancy. And in order to be confident in the result, you need to repeat the research several more times.
