Automated chromatographic system for the simultaneous measurement of plasma pregnenolone and 17-hydroxypregnenolone by radioimmunoassay
A new, simple, rapid and highly practicable automated chromatographic system for the separation, and a sensitive radioimmunoassay system for the subsequent measurement of pregnenolone and 17-hydroxypregnenolone has been developed. Pregnenolone and 17-hydroxypregnenolone were extracted with methylene chloride and separated from cross-reacting steroids by mechanised Sephadex-LH20 multi-column chromatography. Anti-pregnenolone and anti-17-hydroxypregnenolone were obtained by immunising rabbits with pregnenolone-20-oxime-BSA and 17-hydroxypregnenolone-20-oxime-BSA. The lower detection limit of the assay is 0.15 and 0.28 nmol/l for pregnenolone and 17-hydroxypregnenolone, respectively. Normal values for this assay in young male adults, in adult females, and in prepubertal boys and girls were established as a basis for the functional diagnosis of androgen excess syndromes/steroidogenesis defects.
