Abstract
Summary and Conclusions
A method is presented for measuring Cortisol and corticosterone simultaneously in a single specimen of plasma. The steroids are purified by paper chromatography, eluted and measured by fluorometry. Losses incurred during analytical procedure are compensated by application of an isotope dilution correction. The normal range of corticosterone in human beings is 0 to 5 μtg/100 ml, with a mean of 1.3 ± 2.5 μg/100 ml. The normal range for Cortisol is 4.0 to 17.7 μg/100 ml, with a mean of 10.2 ± 3.6 μg/100 ml.
