Term Description

The quantitative ratios of various steroids in urine are measured to diagnose conditions such as 17-alpha-, 21-, and 11-beta hydroxylase deficiencies, pseudohypoaldosteronismus, 3-beta hydroxysteroid dehydrogenase deficiency, corticosterone methyl oxidase deficiency, 11-beta hydroxysteroid dehydrogenase types 1 and 2 deficiency, and 5-alpha reductase deficiency. The results along with clinical symptoms and past medical history are used for the assessment and treatment of the associated deficiency or condition. Below are examples of various disorders and their associated urinary findings:
1. 17-alpha hydroxylase deficiency: (THA+THB+5aTHB)/(THE+THF+5aTHF) > 10, (THA+THB+5aTHB)/(AN+ET) > 10.
2. 21-hydroxylase deficiency: 17HP/(THE+THF+5aTHF) > 0.25, PT/(THE+THF+5aTHF) > 0.25.
3. 11-beta HSD2 deficiency: (THF+5aTHF)/THE > 3
4. 11-beta HSD1 deficiency: (THF+5aTHF)/THE < 0.1
5. 11-beta hydroxylase deficiency: 100*THS/(THE+THF+5aTHF) > 10, 100*THDOC/(THE+THF+5aTHF) > 10
6. Pseudohypoaldosteronismus: 100*THALDO/(THE+THF+5aTHF) > 5
7. 5-alpha reductase: ET/AN > 5, THF/5aTHF > 10
Where AN = Androsterone, ET= etiocholanolone, 17HP= metabolites of 17-OH-progesterone (pregnandiol, pregnantriol, 17-OH-pregnanolone), THA = tetrahydro compound A, THB = tetrahydrocorticosterone, 5aTHB =5 alpha tetrahydrocorticosterone, THE = tetrahydrocortisone, THF = Tetrahydrocortisone, 5aTHF = 5a-tetrahydrocortisone or Allo-tetrahydrocortisone, THS = tetrahydrodeoxycortisol, THALDO = tetrahydroaldosterone, and THDOC =tetrahydrodeoxycortisone

Part Descriptions

LP15564-5   Etiocholanolone
The 5-beta-reduced isomer of ANDROSTERONE. Etiocholanolone is a major metabolite of TESTOSTERONE and ANDROSTENEDIONE in many mammalian species including humans. It is excreted in the URINE. Source: National Library of Medicine, MeSH 2006

LP15564-5   Etiocholanolone
Etiocholanone is a pyrogen, causing fever mediated by interleukin-1 release. Elevated levels in urine have been associated with male pattern baldness. Source: Regenstrief LOINC
