Abstract
An anti-testosterone serum is provided which is highly selective to the measurement of testosterone using radioimmunossay techniques in both male and female plasma without resorting to chromatography even though the plasma may have a high 5.alpha.-dihydrotestosterone content. In addition, the high progesterone concentration normally present in female plasma has no effect on the assay of this plasma. The preferred hapten for producing the serum is 17.beta., 19-dihydroxyandrost-4-en-3-one 19-carboxymethyl ether although related compounds as disclosed herein are also useful.
