Human chorionic gonadotropin is a hormone which is formed in a woman's body during pregnancy. It performs a number of important functions and modern doctors believe that without a sufficient level of concentration of HCG in the blood of childbearing is simply impossible. The lack of growth during the first half of pregnancy may indicate the presence of pathologies. In particular, it may be a sign of the location of the ovum outside the uterus.
Human chorionic gonadotropin is determined in the blood 10-12 days after the onset of fertilization. As a rule, at this period, its concentration is 100-200 honey\ml. Each week it increases in 2-3 times. There is a graph showing normal growth hormone concentrations in the blood throughout pregnancy.
Not pregnant women and healthy men the level of HCG in blood is only 0-15 honey\ml. Concentration in the urine even lower. In most cases, to find in it human chorionic gonadotropin using the standard tests is simply impossible. In this case, you need a more in-depth study.
There are cases when a woman is not pregnant, but HCG levels in her blood. Such analyses often can be observed after undergoing an abortion or if the woman is taking certain hormonal drugs. The doctor didn't jump to conclusions, she should tell him about what dosage hormone treatment she's taking at the moment.
If elevated levels of HCG found in the blood of a man or woman, not to do the abortion and who do not use hormonal drugs, this may indicate a number of serious violations. Most often, these test results indicate the presence in the body of tumors. It is believed that the body responds to the changes taking place in it. A slight increase in the level of chorionic gonadotrophin occurs in women during menopause. However, this increase rarely exceeds the upper limit of the accepted norm.
The negative results of the blood test for HCG you can try to retake it, to eliminate the possibility of error.
Blood for HCG you need to pass in the morning on an empty stomach. If your doctor has prescribed tests for the afternoon, before that it is advisable not to eat for 4 hours.
