Abstract
Aldosterone in 2 ml of plasma was determined by radioimmunoassay. A small modified 10 ml pipette column of LH-20 (0.8×15 cm) was used for separation and 1, 4-diaminoanthraquinone was employed as a marker dye. The application of the small modified column and the marker dye made the separation easy, rapid and accurate. The recovery, precision, accuracy, sensitivity and specificity of the method were satisfactory. This method was considered to be convenient enough for clinical use.
