Human chorionic gonadotropin (HCG) is a glycoprotein hormone secreted by the developing placenta shortly after fertilization. In normal pregnancy, HCG can be detected in serum as early as 7 days following conception. The concentration of HCG continues to rise rapidly, frequently exceeding 100mIU/ml by the first missed menstrual period and peaking in the 30-200,000mIU/ml range by 10-12 weeks into pregnancy. The appearance of HCG soon after conception and its subsequent rise in concentration during early gestational growth make it an excellent marker for the early detection of pregnancy.
The Chemtrue. HCG Combo Test is a rapid test to detect the presence of HCG in urine, serum or plasma specimens in a qualitative format sensitive to 25mIU/ml. The test utilizes monoclonal antibody reagents to selectively detect elevated levels of HCG in urine specimens or in serum specimens. The immunological specificity of the test kit virtually eliminates cross-reactivity interference from the structurally related glycoprotein hormones hFSH, hLH and hTSH at physiological levels.
