Simplification of urinary aldosterone measurement by radioimmunoassay

AUTOR(ES)
RESUMO

An anti-aldosterone serum has been used to measure urinary aldosterone concentration. A single stage of paper chromatography provides an extract of sufficient purity. Further purification by additional chromatography in a different solvent system only improves the purity by 3% ± 8 (SD). Blanks are negligible and recovery of added aldosterone is 104% ± 10 (SD).
