THE GENERATION DIAGNOSTIC SYSTEM
Human chorionic gonadotropin (hCG) is a glycoprotein hormone
secreted by the developing placenta shortly 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 the peak at 100,000-200,000 mIU/ml at the first trimester.
