[Acid labile aldosteronuria. Comparison of radio-immunoassay and colorimetry (author's transl)].
The daily excretion of aldosteronuria was studied in 87 normal or pathological subjects by 3 methods : one, classical, by thin layer chromatography (TLC), based on a modification of Neher's technic, the others, by radio-immunoassay with or without prior extraction of urinary aldosterone (RIA). The normal subjects receiving a daily sodium intake of 150 nmol excrete 24,9 +/- 3,4 nmol/24 hours of aldosterone (TLC) and 23,0 +/- 4,2, 26,3 +/- 3,7 nmol/24 hours (RIA) respectively. These values are not statistically different, RIA of aldosteronuria appears to be a reliable and simple technic and permits one to carry out a large number of examinations within a short period of time with only one technician.
