Abstract
A very sensitive, selective and simultaneous method for the analysis of salivary steroid hormones was examined by discharge-assisted thermospray liquid chromatography mass spectrometry (plasmaspray LC/MS). Plasmaspray LC/MS gave [M + M]+ or [MH — H2O]+ as a predominant ion in most of the steroids in this work and in some cases fragment ions were also observed. Eight salivary steroid hormones, pregnenolone, 17-hydroxypregnenolone, progesterone, 17-hydroxyprogesterone, 11-deoxycortisol, cortisol, aldosterone, and testosterone were identified within 10 minutes using the selected ion monitoring technique in conjunction with plasmaspray LC/MS. Progesterone, 17-hydroxyprogesterone, cortisol, aldosterone and testosterone were detected in 1 mL of saliva from a normal child and two patients with congenital adrenal hyperplasia.
