Human chorionic gonadotropin (hCG) is a glycoprotein hormone secreted by the developing placenta shortly after fertilization. From the onset of pregnancy hCG concentrations in a woman’s serum and urine increase rapidly making the hormone a good marker for pregnancy testing. Seven to ten days after conception the hCG concentration reaches 25 mIU/ml and then increases steadily to reach its maximum between the eighth and eleventh week of pregnancy.1,2,3 The One-Step Early Pregnancy Test is a qualitative, sandwich dye conjugate immunoassay for the determination of human hCG in urine.4,5 The method employs a combination of monoclonal and polyclonal antibodies to selectively identify hCG in test samples with a high degree of sensitivity. In less than 5 minutes, elevated levels of HCG equal to or greater than 25 mIU/mL can be detected.
For the rapid determination of human chorionic gonadotropin (hCG) in human urine. This test kit is for professional use in obtaining a visual qualitative result for the detection of pregnancy.
