Vitamin D (1,25-Dihydroxy) Test at Home in Dubai
Also known as: 1, CALCITRIOL, 25 DIHYDROXY VITAMIN D, 1-25 VITAMIN D
Included
About the Test
This test measures 1,25-dihydroxyvitamin D (calcitriol), the fully active hormonal form of vitamin D produced mainly by the kidneys. It is a specialised test, not the routine vitamin D check, and is used to investigate specific problems with calcium regulation, certain kidney disorders, parathyroid conditions and some causes of high calcium such as granulomatous diseases. Because it behaves differently from the storage form, it is ordered by doctors for particular clinical questions rather than for general screening.
What is it? A blood test measuring the active vitamin D hormone 1,25-dihydroxyvitamin D, also known as calcitriol.

No. The routine test measures 25-hydroxyvitamin D, your storage level. This measures the active hormone calcitriol and is used for specific calcium, kidney and parathyroid investigations, usually on a doctor's request.
Fasting is not required for this test. Follow any particular instructions from the doctor who ordered it, and continue your usual medicines unless told otherwise.
For general screening of vitamin D status, the standard 25-hydroxyvitamin D test is the right choice. This active-form test is best ordered when a doctor is investigating a specific problem.
Active vitamin D is closely tied to calcium, phosphate, kidney function and parathyroid hormone, so your doctor reads it together with those values to reach the correct conclusion.
