The presence of such changes in the body as a woman: the absence of a period of more than 1 week, nausea in the morning, weakness, irritability or changes in taste preferences should prompt a woman to take tests for pregnancy. Of course, you can simply go to the gynecologist or obstetrician who, by palpation or internal examination, will determine the presence of a fetal egg or fetus in the uterus. But the most reliable information about the period of gestation and its nuances will give exactly a blood test for determining pregnancy.
Modern moms have access to a so-called rapid pregnancy test, the action of which is based on the reaction of its components to the hormone content of hCG in the woman's urine. It is not always true, because the term may be too small or the hormone content insufficient to determine the presence of fertilization. There is such a classification of pregnancy tests :
- in the form of strips;
- Tablet;
- electronic or inkjet.
However, in any case, it is necessary to confirm the result obtained by submitting a blood test and a pregnancy test in the laboratory, which will make it possible to establish the presence of fertilization at the earliest possible dates and at the first signs. In medical practice, it is called the analysis of the blood for pregnancy hCG, because it is based on the determination of the presence in the patient's blood of the human chorionic gonadotropin hormone. It occurs in the female body with the formation of fetal membranes of the embryo, one of which is called the chorion.
Features of pregnancy determination by blood analysis
This method is 100% effective, but there are exceptions to the rules, when an unreliable result is possible. For example, if the patient has been using hormonal drugs for a long time or has had a bladder drift. A blood test can establish fertilization literally a day after sexual intercourse and fully characterize it.
The early period of the analysis of the blood for pregnancy gives the woman the opportunity to make the right decision - whether she will bear the child or not.
