hCG

The hCG Total Quantitative Test measures human chorionic gonadotropin levels in blood to confirm pregnancy and monitor its progression. It provides exact hCG values, helping detect ectopic pregnancy, miscarriage risk, and abnormal growths like trophoblastic disease. 

It is the hormone detected in pregnancy tests and is also used medically to treat certain conditions like infertility in men and to monitor and treat certain tumors, such as those from germ cell cancers. High or low levels can be indicators of complications like miscarriage, ectopic pregnancy, or gestational trophoblastic disease.
