LH Rapid Test midstream

Introduction:
The LH Rapid Test midstream is an immunochromatographic assay designed for the rapid determination of luteinizing hormone (LH) in urine. The test is used to obtain a visual qualitative result.

Principle:
The LH Rapid Test midstream is a lateral flow chromatographic immunoassay based on the principle of the double antibody–sandwich technique. The membrane is precoated with anti-LH antibodies on the test line region. In the test procedure, the liquid sample is allowed to migrate through the absorbent area. If LH is present, labeled antibody-dye conjugate binds it, forming an antibody-antigen complex. As the reaction mixture continues to flow along the test membrane, the complex binds to the anti-LH antibody in the test (T) zone of the membrane, and produces a pink-rose color band. Unbound conjugate binds to the reagents immobilized in the control (C) zone producing a pink-rose color band, demonstrating proper performance of the test.
