Optical Q - Immunoassay For the Quantitative Determination of beta-hCG

Human chorionic gonadotropin (hCG) is a glycoprotein hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo, which eventually, forms the placenta after implantation. hCG can be detected in the urine and serum of pregnant women as early as 6 to 15 days after conception. The concentration of hCG increases to 50 mIU/ml one week post implantation and reaches to about 100 mIU/ml at the time of the first missed menstrual period and peaks at 100,000-200,000 mIU/ml at the first trimester. Beta-hcG tests helps in confirming a pregnancy, identifying an ectopic pregnancy, and monitoring a pregnancy that may be at risk of failing.
