Gonadotropin chorionic experts call the hormone of pregnancy: it begins to be produced in the body of a woman after successful fertilization of the egg. For the development of its responsible tissues of the embryo, more precisely - the cells of the chorion, the shell of the embryo. It is the chorionic gonadotropin already in the early stages of pregnancy that signals its onset - already on the 6-10th day after fertilization, the results of blood tests will be positive. By the presence or absence of this hormone in the blood, pregnancy is diagnosed in women who carefully plan pregnancy and have some difficulties with it. Later on, by measuring the parameters of gonadotropin in chorionic pregnancy, the doctor will be able to monitor the course of pregnancy, diagnose certain threats for her.
For example, gonadotropin chorionic during pregnancy plays one of the most important functions for maintaining it - this hormone is responsible for the formation of the hormones required during pregnancy, namely progesterone and estrogens. Any deviation - an increase or decrease in the level of chorionic gonadotropin in the body - indicates that there are some relatively dangerous conditions for the further development of pregnancy.
For example, increased gonadotropin in pregnancy can be a signal for the development of toxicosis, gestosis, a testimony of diabetes maternal diabetes. In addition, the level of this hormone increases if pregnancy is characterized by multiple births - the content of gonadotropin in this case increases in proportion to the number of children in the womb. But the reduced rates of gonadotropin chorionic in pregnancy can be a sign of an ectopic or undeveloped pregnancy, warn of a threat of miscarriage, signal a delay in the development of the fetus.
Immediately after the beginning of pregnancy, the level of chorionic gonadotropin is constantly and rapidly increasing: during the first trimester it doubles every 2-3 days. The maximum level of chorionic gonadotropin in pregnancy is reached by 10-12 weeks, then it gradually begins to decrease and maintains a constant throughout the second half of pregnancy. The indications for regular check of the hCG level in the blood during pregnancy become dynamic observation of pregnancy, the desire to exclude the presence of an ectopic pregnancy, the threat of miscarriage and suspicion of an undeveloped pregnancy, the prenatal diagnosis of the defects of the fetus. It should be borne in mind that, whatever the result of the analysis on gonadotropin chorionic in pregnancy, an adequate interpretation can be done only by a qualified doctor, who knows the results of all other surveys and is aware of all the subtleties of a pregnancy.
They give an analysis for HCG by screening blood from the vein, preferably in the morning and only on an empty stomach. If, for some reason, the blood is surrendered at other times of the day, it is necessary to refrain from eating for 4-6 hours before taking the test. In this case, the doctor must definitely inform about taking hormonal drugs, if any. If the gonadotropin-chorionic test for pregnancy is given to identify possible fetal pathologies, you should be aware that a one-time analysis can not yet be considered a 100% indicator. For the diagnosis to be reliable, it is necessary to take a blood test for HCG not once, but also in conjunction with some other markers.
