Lab Test Catalogue

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.

Measures albumin, the most abundant protein in blood. Low levels indicate liver disease, malnutrition, kidney disease, or chronic inflammation.

Aldosterone is a steroid hormone produced by the adrenal glands that plays a central role in regulating blood pressure, sodium retention, and potassium excretion. It acts on the kidneys to retain sodium and water while excreting potassium, directly influencing fluid balance and blood pressure. This test measures aldosterone levels in the blood and is most commonly ordered to investigate primary hyperaldosteronism (Conn's syndrome) — a condition where the adrenal glands produce excess aldosterone independent of normal regulatory signals. Primary hyperaldosteronism is one of the most underdiagnosed causes of treatment-resistant hypertension and is far more prevalent than traditionally recognized. Elevated aldosterone relative to renin (assessed via the aldosterone-to-renin ratio) is the hallmark finding in primary hyperaldosteronism and may indicate an adrenal adenoma or bilateral adrenal hyperplasia. Low aldosterone levels may be seen in adrenal insufficiency (Addison's disease), hyporeninemic hypoaldosteronism, or as a side effect of certain medications. This test is commonly ordered alongside plasma renin activity or direct renin concentration for proper interpretation. It is most relevant for individuals with difficult-to-control hypertension, unexplained low potassium (hypokalemia), adrenal incidentaloma, or a family history of primary hyperaldosteronism or early-onset hypertension.
