Measures the levels of 11-deoxycortisol, a steroid precursor involved in cortisol production. It is used to assess adrenal function and diagnose conditions like congenital adrenal hyperplasia (CAH) or adrenal insufficiency. Elevated levels may indicate enzyme deficiencies affecting cortisol synthesis, while low levels suggest impaired adrenal activity
Serum
0.5 mL
Red-top tube or gel-barrier tube
No special preparation is required for this test. You may eat, drink, and take your medications as normal, unless instructed otherwise by your healthcare provider.
