Human chorionic gonadotropin (hCG), a glycoprotein hormone is secreted by synciotrophoblastic cells of the placenta, after fertilization. Following conception approximately after 6-8 days, hCG is released and its concentration doubles every 1.7 days. The levels of hCG rise rapidly reaching peak levels after 60-80 days. The appearance of hCG in urine soon after conception makes it an ideal marker for the early detection and confirmation of pregnancy. However elevated hCG levels are frequently associated with trophoblastic and non-trophoblastic neoplasms, hence these conditions should be considered before a diagnosis of pregnancy can be made.
