82894-7Pregnanediol/Tetrahydrocortisone+tetrahydrocortisol+5-alpha tetrahydrocortisol [Molar ratio] in UrineActive

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

LP15815-1   Pregnanediol
An inactive metabolite of PROGESTERONE by reduction at C5, C3, and C20 position. Pregnanediol has two hydroxyl groups, at 3-alpha and 20-alpha. It is detectable in URINE after OVULATION and is found in great quantities in the pregnancy urine. Source: National Library of Medicine, MeSH 2006

LP15815-1   Pregnanediol
Allo-pregnanediol (5α-pregnane-3α,20α-diol), pregnanolone (5β-pregnane-3α-ol-20-one), epipregnanolone (3β-hydoxy-5β-pregnan-20-one) and pregnanediol (5ß-pregnane-3α,20α-diol) are metabolites of progesterone. During pregnancy and in certain phases of the menstruation cycle, these metabolites are excreted at higher levels. They are also important markers in steroid profile analysis in urine for the evaluation of an adrenal 21-hydroxylase-deficiency. Source: Regenstrief LOINC
