title: Immunological interference of the synthetic aromatase inhibitor 1,4,6-androstatriene-3,17-dione (ATD) and its metabolite(s) in the radioimmunoassay for testosterone.
abstract: Radioimmunoassay (RIA) for testosterone (T) in unchromatographed plasma extracts from ATD-treated rats gave spuriously high values for T. Cross-reaction and chromatographic studies subsequently showed that ATD and, to a much greater extent, its metabolite(s) were responsible for this overestimation. Celite column chromatography proved to be an effective way of separating T from ATD and its product(s) of metabolism.
