Simultaneous estimation of urinary steroids by semi-automated gas chromatography. Investigation of neo-natal infants and children with abnormal steroid synthesis

Clin Chim Acta. 1976 Jun 1;69(2):267-83. doi: 10.1016/0009-8981(76)90505-2.


Development of a method for multicomponent analysis of urinary steroids on open-tubular columns is described. The urinary steroid conjugates were hydrolysed enzymatically, extracted on Amberlite XAD-2 columns, purified on columns of Sephadex LH-20, then analysed as methyloxime trimethylsilyl ethers on a gas chromatograph on which up to 24 samples may be automatically injected. All major urinary steroids from 17-oxosteroids to cortisol metabolites were analysed and these were quantified relative to internal standards, 5alpha-androstane-3alpha, 17alpha-diol and cholesteryl butyrate added to the samples prior to derivatisation. The precision of the full technique and reproducibility of repetitive automatic solid injection was found to be acceptable for the purpose of profile analysis. Examples of urinary steroid profiles in normal infants and infants with disorders of adrenal steroid production and excretion are given.
