HCG Pregnancy Test Cassette

Description

Intended Use The Pregnancy One Step Rapid Test Cassette is a rapid, one step test for the qualitative detection of human chorionic gonadotropin (hCG) in urine, as an aid for the early detection of pregnancy. The test is intended for in vitro diagnostic self-testing.
  Principle The Pregnancy One Step Rapid Test Cassette adopts the principles of double antibody sandwich method and immunochromatography to test the human chorionic gonadotropin (hCG) in the urine. The membrane is pre-coated with anti-hCG antibodies in the test region (T) and anti-mouse antibodies in the control region (C). During testing, the urine sample reacts with the colored conjugate (mouse anti-hCG antibody colloidal gold conjugate) which has been pre-coated on the test strip. The mixture then migrates upward on the membrane to react with anti-hCG antibodies in the test region and generate a red line. Presence of the red line indicates a positive result, while its absence indicates a negative result. Regardless of the presence of hCG, as the mixture continues to migrate across the control region, a red line at the region will always appear. The presence of this red line serves as verification for sufficient sample volume and proper flow and as a control for the reagents.
