Immunoradiometric assay (IRMA) monitoring of periovulatory lutropin in serum

Sauer, Mark V.; Gorrill, Marsha Jan; Buster, John E.

In an immunoradiometric assay (nu) for lutropin (luteinizing hormone, LH) recently developed by RSL/Immunchem Corp., Carson, CA, specific monoclonal antibodies directed against two distinct immunogenic sites of the LH molecule are used. The assay is used primarily to detect the preovulatory rise and peak of LH in serum as a predictor of ovulation time in women.
