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.

Includes Potassium, Sodium, Chloride, Blood Urea Nitrogen (BUN), Creatinine with eGFR, Calcium, and Glucose. ⚠️ Important — Please Read Before Ordering This panel includes Potassium (KS), which has a 48-hour specimen stability window. Because samples are shipped via FedEx to Mayo Clinic Laboratories, a courier delay could cause the Potassium result to be cancelled if the specimen exceeds its stability window before processing. If Potassium is cancelled due to a shipping delay, all other markers in this panel will still be collected and reported. You will not be charged for any cancelled test. To minimize this risk, this panel must be booked for a Tuesday morning collection appointment so specimens ship the same day and arrive at the lab within the stability window. By adding this panel to your cart you will be asked to acknowledge this risk.
