A modified method for estimating 17-hydroxycorticosteroids in plasma

Abstract
A modification of the method of D. H. Nelson and L. T. Samuels, [Jour. Clin. Endocrin. 12, 1952] for estimating 17-hydroxycorticosteroids in plasma is descr. The method is sufficiently simple for clinical use. About 1/3 to 1/2 of the material estimated appears to be 17-hydroxycorticosterone, the remainder was more polar compounds.
