LH one step Ovulation Rapid Test   *CE Marked

The LH Ovulation Test (Urine) is a rapid chromatographic immunoassay for the qualitative detection of luteinizing hormone (LH) in urine to aid in the detection of ovulation.

The LH One Step Test is a colloidal gold enhanced immunoassay for qualitative or semi-quantitative determination of hLH in urine. The nitrocellulose membrane used as solid phase was precoated with sheep anti-hLH on the test region. During the test, the urine sample is allowed to react with a colored conjugate  (mouse anti-hLH monoclonal antibody-colloidal conjugate) which was pre-dried on the test strip. Upon the dropping of the urine sample, the mixture will move along the strip through a capillary action. If hLH is present in the sample, a red color  band with a specific antibody-hLH colored immunogold conjugate complex will form on the test band region. On the other hand, a light color band  will always appear at the control region. This control band  serves as a reference of the color intensity of about 25 mIU/ml hLH. When the intensity of the test band is equal to or stronger than that of the control/reference band, the test result is positive, indicating that the LH surge is likely in progress.
