Determination of 17?-hydroxypregnenolone sulfate and its application in diagnostics
Original language description
New combined radioimmunoassay for determination of 17-hydroxypregnenolone sulfate (17-PregS) involving the hydrolysis of analyte by methanolysis was developed. 17-PregS, in addition to being secreted by the adrenals, is also formed by peripheral sulfoconjugation of 17-hydroxypregnenolone (17-Preg) or directly by hydroxylation of pregnenolone sulfate with 17-hydroxylase/C17-20lyase. The measurement of 17-PregS can be used as a tool for detection of enzymatic deficiency particularly in pregnancy and for detection of congenital adrenal hyperplasia or gonadal dysfunction. The serum levels of 17-PregS, 17-Preg, dehydroepiandrosterone, dehydroepiandrosterone sulfate, pregnenolone and pregnenolone sulfate were measured in different age groups of human and inpregnant women respecting the age of gestation. The levels of 17-PregS are approximately three times higher than the levels of free 17-Preg in all subject groups. The levels of 17-PregS during pregnancy reached the local minimum in the 3r
