HCG is a glycoprotein hormone secreted by the developing placenta during pregnancy. The concentration of HCG in serum is approximately
equal to the concentration in urine. The concentrations of hCG in urine and serum continue to rise during the first trimester of pregnancy to as                                              HCG Concentration (mIU/ml)             0    25    50     100     500
