Abstract
Using gas chromatography/mass spectrometry we have developed a method for the simultaneous determination of six plasma steroids: testosterone, 4-androstenedione, 17 alpha-hydroxyprogesterone, 5 alpha-androstane-3 alpha,17 beta-diol, 5 alpha-dihydrotestosterone, and dehydroepiandrosterone. For each analyte, a deuterium-labeled internal standard was used for quantification. Due to the high isotopic purity of our standards, no complex corrections for isotope contributions were necessary. The procedure provides a sensitive and specific technique with good accuracy and precision.
