BHCG (beta HCG) is the name of a pregnancy test that checks the levels of the hormone HCG in the blood. HCG stands for Human Chorionic Gonadotropin which stands for Human Chorionic Gonadotrophin .The hormone HCG is unique to pregnancy. It is produced after the attachment of the embryo to the wall of the uterus. It is through the high concentration of this hormone in the blood and urine that you can detect a pregnancy.
The function of HCG is to order the ovary to produce estrogen and progesterone, so that when they reach the pituitary, the production of other hormones that stimulate ovulation ceases. In this way, the menstrual cycle is suspended.
The HCG beta test result indicates whether the woman is pregnant (greater than 50 mUl / mL) and the stage of pregnancy. When the HCG dosage in blood is less than 49.9 mIU / mL, the test should be repeated after two or three days for a conclusive examination.
The BHCG test is reliable and can only be done in a clinical laboratory. The most common pregnancy test is done through the urine and can be performed at home.
