The polarographic estimation of steroid hormones. 6. Determination of individual adrenocortical hormones in human peripheral blood

Abstract
Adrenocortical steroids were extracted from 2.0 ml. blood plasma by partition chromatography and measured with a micropolarographic technique. 80-90% recovery was obtained with added steroids. Normal values (mg./100 ml. plasma) were: 11-17-hydroxycorticosterone, 8.4. Values were increased by pregnancy and ACTH.
