One of the most important issues for women, which in due time has not come menstruation, and there are any subjective complaints - if there is a pregnancy. In modern conditions to answer this question allows rapid analysis of pregnancy. It works on the basis of urine analysis, wherein by means of special reagents hCG determined content.

Based on what conduct rapid diagnosis

The proposed test systems for the diagnosis of pregnancy, have high confidence. Depending on the test system, this percentage is 92-99%. Any urine test is based on a chemical reaction of the reagent with the active molecules of the hormone human chorionic gonadotropin. This reaction is considered positive if the test is intense staining of the two strips (if it is a very simple test system in the form of strips). If there is no pregnancy, and no release of the pregnancy hormone in the urine, the reaction will be negative, and the second stripe appears.

But not always the absence of a chemical reaction during the test indicates the absence of pregnancy. Pregnancy can successfully develop only gestational age will be small. In this case there is no sufficient of the hormone in the female body, so the test can not respond to this concentration of hCG and showed negative results. It is important not to hurry with the conduct of the test and not do it too soon. The best reference for the diagnosis of pregnancy - a delay of the next menstrual period within five days or one week.

Types of rapid tests

The proposed test system for rapid diagnosis are very diverse. There are several types of tests:

• a test system in the form of strips;
• Tablet tests;
• jet tests;
• electronic tests.

Women most often use test strips for diagnosing pregnancy. They are among the most simple, convenient and affordable tests. The woman must be lowered to a sufficient depth in the strip of the reagent container with urine and wait for five to ten minutes. Improved and accurate tests are considered to be the last generation jet. The percentage of reliability of the results is 99%. The name they got from the technique of performing diagnostics - a woman should substitute test directly under the stream of urine. To obtain the most accurate result is better to get this kind of test, despite the fact that it is more expensive than other test systems.

The hormone hCG begins to produce immediately after the implantation of the ovum in the lining of the uterine wall. Its level increases throughout the first trimester. The hormone content of urine is somewhat different from the concentration in the blood, so the most significant is the definition of the concentration of hCG in blood serum. Urinary test can be attributed to the rapid qualitative diagnostic methods and on the analysis of blood is obtained quantitative analysis.

To properly evaluate the content of the hormone in the blood, you should know the presumable term of pregnancy. Each week characterized by its quantitative indicators on which to judge the development of the pregnancy and the development of pathological changes. As urinary rapid test is also possible to conclude unsuccessful pregnancy. Weak staining second dough strip is in some cases a sign threat interrupts. This explains the need for timely referral to a specialist, if a woman has received the results of the study. In threatening condition for the development of the pregnancy should undergo a course of treatment, preferably in a specialized hospital. As of therapeutic measures on the basis of changes in the test results can be judged on whether there is the effect of the therapy.
