HCG (human chorionic gonadotrophin) is a hormone secreted in pregnancy that is made by the developing embryo soon after conception and later by the syncytiotrophob last (part of the placenta) to maintain the fetal viability preventing the disintegration of the corpus luteum of the ovary and thereby maintaining progesterone production that is critical for a pregnancy in humans; it also affects the immune tolerance of the pregnancy. HCG is excreted in the urine of pregnant women. Detection of this hormone in urine or serum is an easy first method of diagnosis of pregnancy.
The HCG (human chorionic gonadotropin) is produced during pregnancy. It is made by cells that form the placenta, which nourishes the egg after it has been fertilized and becomes attached to the uterine wall. Levels can first be detected by a blood test about 11 days after conception and about 12 - 14 days after conception by a urine test. In general the hCG levels will double every 72 hours. The level will reach its peak in the first 8 - 11 weeks of pregnancy and then will decline and level off for the remainder of the pregnancy.
