A blood test for HCG to diagnose pregnancy
Human chorionic gonadotropin is a hormone that can be synthesized in the human body. In the absence of certain conditions in the body, HCG is not produced. Its content in the blood in this case does not exceed 2.5-5 honey\ml. At the onset of pregnancy the level of human chorionic gonadotropin in the blood begins to rise rapidly. This occurs immediately after the implantation of a fertilized egg in the uterus.
A week after embryo implantation the concentration of HCG in the blood is 100-150 honey\ml. during the first half of pregnancy and this figure is increasing rapidly. Every 3 days it rises to about half in comparison with the value of the previous figure.
Thanks to the development of human chorionic gonadotropin, it becomes possible to diagnose pregnancy at a very early time. The blood analysis allows to establish its presence in a week after the alleged conception. Increasing the concentration of HCG in comparison with the norm can be determined in the urine, but this is possible only from the first day of menstruation, since the content of this hormone in biological fluids is not as high as in the blood.
For the determination of the hormone in the urine to be tested in the laboratory is not required. You can use a test designed for use at home.
From 20 weeks of pregnancy, the HCG level in the blood and the urine ceases to increase and then begins to decrease. If this happens at an earlier time, in this case you can suspect a number of serious pathologies. This may indicate the development of an ectopic pregnancy, about the sinking of pregnancy and allows timely detecting the threat of inadvertent interrupts.
If the HCG level is elevated, and pregnancy is not
There are cases where analysis shows an increase in the level of gonadotropin in the blood of non-pregnant women and even in men. Concentration can be increased if recently, a woman underwent an abortion or she accepts hormonal drugs. That's why doctors usually ask patients what drugs they use at the moment. If a woman drinks hormones, the analysis on hgch will be uninformative.
Increasing the concentration of gonadotropin in the blood may also indicate development of fairly serious diseases. Most often it is necessary to observe when the human body is affected benign or malignant.
