A woman who is of reproductive age and is living a regular sexual life, makes the test in the first place with the aim to find out if her pregnancy. In most cases, there are two options result, i.e. positive or negative. Sometimes there is a situation when the test gives a weak positive result on a pregnancy. Possible doubts about the presence or absence of a pregnancy can allow only gynecological examination.

Interpretation of the results of low positive test

During the urinary test reaction occurs between the application of the test strip and reagent molecules of the hormone human chorionic gonadotropin, which is excreted in the urine during pregnancy. If a woman has a pregnancy, such a reaction is manifested by staining the strips (the test is positive).

The color intensity is determined by several factors, such as the sensitivity of the test system, for the period of pregnancy, the time of the study. The most common urinary tests which are available as special test strips, pregnancy occurs in the presence of the emergence of two distinct, uniformly colored stripes. But painting stripes may be uneven when one bar is visible clearly and the other not. This test result is considered to be weakly positive.

The color intensity will depend on its duration. It is a mistake to consider such a result is negative.

What determines the weak positive test result

Pregnancy in most clinical cases gives a positive urinary test (reliability test systems certain reaches 99%). In cases where the pregnancy is at the very early stages of proceeds with the phenomena threatening miscarriage Miscarriage - is more common than you think This can lead to a low positive response test. With the threat of termination of pregnancy is a change of the hormone HCG, which is produced by cells growing chorionic. This is most clearly when the phenomena of detachment Chorion, which is a sign of miscarriage started (it will be manifested clinically appearance of pain and abnormal vaginal discharge).

Weakly positive test in this case speaks of unfavorable pregnancy complications and available. Pregnancy should be admitted to hospital, she was appointed by the therapy, which aims to preserve the pregnancy. Subsequently, it can be observed that after the removal of threats to the qualitative analysis to identify the hCG will already have a uniform coloration of the two strips.

Women believe that it is necessary as long as possible to keep the strip in the urine and then there will be more reliable results. But this is a mistake. By increasing the contact time of the reactant in the urine is released dye, however, in the absence of pregnancy test can be interpreted as a weak positive.

The test must be conducted in compliance with certain requirements:

• strip to properly immerse in a container of urine;
• stand for five to ten minutes;
• it is very important to choose the sensitivity of the test system to match with hormonal activity, that is, levels of the hormone hCG in a woman's body corresponded to the sensitivity of indicators specified in the test.

In doubtful cases, in order to fully ascertain the presence of pregnancy, it is necessary to conduct a second study in a week. If the period of pregnancy is still not large enough, then after this time it will be clearer staining the second strip on the test.
