About Vitamin D 25-Dihydroxy (Calcitriol) Test in Murrieta
Understanding the 25-dihydroxy (calcitriol) form of vitamin D
Vitamin D is a fat-soluble nutrient that supports calcium balance, bone health, and normal muscle and immune function. The body converts vitamin D through a series of steps, and calcitriol is the final, hormonally active metabolite.
The 25-dihydroxy (calcitriol) test measures this active form in the blood. Because its production is tightly regulated by the kidneys, the result can offer information that differs from tests of other vitamin D metabolites.
Clinicians may order this test when evaluating hypocalcemia, when monitoring renal disease, or when other vitamin D measurements do not fully explain a patient's clinical picture. Results are typically interpreted alongside calcium, phosphorus, parathyroid hormone, and kidney function tests.
