The LH Rapid Test Device (Urine) is a rapid visual immunoassay for the qualitative, presumptive detection of luteinizing hormonein human urine specimens. This kit is intended for use as an aid in the detection of ovulation.
Principle of Ovulation (LH) Test Cassette
The LH Rapid Test Device (Urine) detects human luteinizing hormone through visual interpretation of color development on the strip. Anti-LH antibodies are immobilized on the test region of the membrane, and anti-mouse antibodies immobilized on the control region. During testing, the specimen reacts with anti-LH antibody conjugated to colored particles and precoated onto the sample pad of the strip.The mixture then migrates through the membrane by capillary action, and interacts with reagents on the membrane.If there is sufficient LH in the specimen,a colored band will form at the test region of the membrane. The presence of this colored band indicates a positive result, while its absence indicates a negative result. The appearance of a colored band at the control region serves as a procedural control, indicatingthat the proper volume of specimen has been added and membrane wicking has occurred.
