The active form of Vitamin D, also known as Calcitriol, is the biologically potent version that your kidneys produce from the storage form (25-OH Vitamin D). While the standard Vitamin D test measures stored Vitamin D, this test measures the activated hormone that directly regulates calcium absorption, bone metabolism, immune function, and cell growth.

11-Desoxycortisol is a steroid hormone produced in the adrenal cortex and serves as the direct precursor to cortisol in the cortisol synthesis pathway. Under normal circumstances, it is converted rapidly to cortisol by the enzyme 11-beta-hydroxylase, meaning baseline levels in the blood are very low. This test is primarily used in the evaluation of adrenal function and steroid biosynthesis disorders. It is most commonly ordered as part of a metyrapone stimulation test — a diagnostic procedure used to assess pituitary-adrenal axis function and the adrenal gland's ability to respond to ACTH stimulation. A failure of 11-Desoxycortisol to rise appropriately after metyrapone administration indicates impaired adrenal or pituitary reserve. Elevated baseline 11-Desoxycortisol levels may indicate congenital adrenal hyperplasia (CAH) due to 11-beta-hydroxylase deficiency, one of the less common forms of CAH that can present with hypertension, virilization in females, and precocious puberty. This is a specialized endocrinology test typically ordered in consultation with an endocrinologist investigating adrenal insufficiency, CAH, or pituitary dysfunction.
