DETERMINATION OF DEHYDROISOANDROSTERONE AND 17-KETOSTEROIDS

Determination of dehydroisoandrosterone and 17-ketosteroids.

Methods for the quantitative determination of steroids have been developed, based on their specific chemical or physicochemical properties. The Zimmermann reaction (1) and the Kober reaction (2) have been found useful in the quantitative determination of certain individual steroids occurring in urine. Modifications of these reactions have been reported by Callow et al. (3), Holtorff and Koch (4...

Urinary excretion of 17-ketosteroids in children.

Determination of the urinary excretion of 1 7-ketosteroids (17-oxosteroids) is the most important laboratory test in the investigation of endocrine disorders involving the adrenal cortex and gonads in children. The normal range of excretion varies with the method employed, since non-steroidal pigment may to a greater or lesser degree be measured as 17-ketosteroid. It is important therefore to k...
