Abstract
The present invention relates to the measurement of estradiol using competitive immunoassay methods. The inventors unexpectedly discovered that estrone and its derivatives conjugated to a label is a particularly effective tracer when used in conjunction with estradiol specific antibodies to determine estradiol levels in fluid samples. The present invention also utilizes 5.alpha.-dihydrotestosterone to enhance the assay performance.
