Radioimmunoassays for aldosterone and deoxycorticosterone in plasma and urine.
Radioimmunoassays for aldosterone and deoxycorticosterone (DOC) are described in which a simple separation procedure using ammonium sulfate stabilization of bound steroid and extraction of free steroid into toluene scintillant allows an "in vial" assay without mechanical separation of the two phase system. Extraction and thin layer chromatographic methods for purification of aldosterone and DOC are free of solvent and plate blank effects. Normal values are given for unconjugated aldosterone and DOC in urine, for aldosterone and DOC in plasma and for aldosterone 18-glucuronide in urine.
