The urinary samples for determination of urinary free cortisol (UFF), urinary
free cortisone (UFE), urinary total cortisol (UTF), urinary total cortisone
(UTE), and their metabolites 5alpha- or allo-tetrahydrocortisol (aTHF),
5beta-tetrahydrocortisol (THF), and tetrahydrocortisone (THE) were analyzed
using a validated LC-MS/MS method. The ratio
(aTHF+THF)/THE was used to indirectly assess 11beta-HSD1
inhibition in the liver.
