Beta Hcg

Beta hCG, also called hCG blood test, is a test that detects the levels of human chorionic gonadotropin hormone (hCG) in the blood. The cells in the placenta produce this hormone during pregnancy. This hormone can be detected in blood after 11 days of conception, and the levels double every 48 to 72 hours. hCG levels reach their peak between 8 and 11 weeks of pregnancy.
