Order Vitamin D 25-Dihydroxy (Calcitriol) TestThe Vitamin D 25-Dihydroxy (Calcitriol) Test measures the concentration of calcitriol, the biologically active form of vitamin D, in the bloodstream. This assay is distinct from the more commonly ordered 25-hydroxyvitamin D test, which assesses overall vitamin D stores. Because calcitriol is produced primarily in the kidneys, its measurement offers specific insight into renal conversion of vitamin D and calcium regulation.
About Vitamin D 25-Dihydroxy (Calcitriol) Test in Rocky Mount
Calcitriol is the hormone responsible for maintaining calcium and phosphate balance in the body.
Calcitriol, or 1,25-dihydroxyvitamin D, is formed when the kidneys convert 25-hydroxyvitamin D into its active form. This conversion is tightly regulated by parathyroid hormone, serum calcium, and phosphate levels.
The test is typically used when a patient has unexplained hypocalcemia, suspected kidney disease, or an abnormal calcium balance that cannot be explained by standard vitamin D testing. It helps distinguish between problems of vitamin D storage and problems of vitamin D activation.
Results are interpreted alongside other laboratory values such as calcium, phosphate, parathyroid hormone, and creatinine. A low calcitriol level may indicate impaired kidney function or a defect in the enzyme responsible for its production, while an elevated level may occur in certain granulomatous diseases or hypercalcemia of malignancy.
