why HCG detection important? Aug 10, 2022

What is HCG?

Human chorionic gonadotropin (hCG) is a hormone normally produced by the placenta. If you are pregnant, you can detect it in your urine. Blood tests measuring hCG levels can also be used to check how well your pregnancy is progressing.

What is beta HCG test?

Beta human chorionic gonadotropin (HCG) is a hormone produced by the placenta during pregnancy, and is typically detected in the blood. A beta HCG test is a blood test used to diagnose pregnancy, and usually becomes positive around the time of the first missed period.


HCG is a glycoprotein hormone secreted by the developing placenta during pregnancy. HCG appears in blood shortly after conception, and continues to increase during the early stages of pregnancy, making it an excellent indicator for the detection of pregnancy. And the normal pregnancy is diagnosed according to the HCG levels in blood. The Diagnostic Kit is based on immunochromatography and can give a result within 15 minutes.


The membrane of the test device is coated with anti HCG antibody on the test region and goat anti rabbit IgG antibody on the control region. Lable pad are coated by fluorescence labeled anti HCG antibody and rabbit IgG in advance. When testing positive sample, the HCG antigen in sample combine with fluorescence labeled anti HCG antibody, and form immune mixture. Under the action of the immunochromatography, the complex flow in the direction of absorbent paper, when complex passed the test region, it combined with anti HCG coating antibody, forms new complex. HCG level is positively correlated with fluorescence signal, and the concentration of HCG in sample can be detected by fluorescence immunoassay assay.
