Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone normally produced by placenta during pregnancy. Structurally intact HCG molecule is consists of two non-covalently linked polypeptide subunits, the alpha and beta chain subunits. Measurements of intact HCG and of the alpha subunit of HCG appear to give similar results in blood and urine but not the levels of beta subunit. Normally Free β-HCG concentration in fetal serum increases and reaches its maximum on the tenth week of pregnancy then it starts to decrease. Fetus with Down Syndrome increase maintenances free beta-subunits in the maternal serum in 2 times in comparison with value median line for each fetal phase. 

GonadotropinEIA-free beta-hCG kit is intended for the quantitative determination of free beta subunit of human chorionic gonadotropin in human serum.
