3b-Allotetrahydrocortisol is one of the tetrahydrometabolites of cortisol. The 11-beta-hydroxysteroid dehydrogenase (11beta-HSD) is responsible for the interconversion of both the hormonally inactive cortisone and the active cortisol, which has implications in the pathogenesis of numerous diseases, as reflected in the ratio of tetrahydrometabolites of cortisol. (PMID: 16310418). The daily excretion of allotetrahydrocortisol is above normal in hyperthyroid patients; In contrast, in hyperthyroidism the excretion is diminished below normal levels to approximately half that of normal subjects. (PMID 13906284). A decreased activity of the enzyme 11beta-HSD produces a pattern of urinary steroid metabolites with an abnormal elevation of tetrahydrocortisol and allo-tetrahydrocortisol compared to tetrahydrocortisone; this pattern of steroid excretion is essential for the diagnosis of the syndrome of apparent mineralocorticoid excess type 1.

The urinary Tetrahydrocortisol/Tetrahydrocortisone ratio decreases with increasing 11β-hydroxysteroid dehydrogenase (11β-HSD) activity[1][2].
