Details

Two forms of vitamin D can be measured in the blood. 1,25-dihydroxyvitamin D is the active form of vitamin D. The body converts the relatively inactive form, 25-hydroxyvitamin D, to 1,25-dihydroxyvitamin D. The Vitamin D 1,25 Dihydroxy Blood Test measures levels of the active hormone form of vitamin D in the blood, which may be necessary if a condition that produces excess vitamin D is suspected. Such diseases include sarcoidosis and some forms of lymphoma. High levels can be indicative of such conditions, or of excess parathyroid hormone.

The test may also be ordered to evaluate the effectiveness of supplementation treatment for vitamin D, calcium, phosphorus, or magnesium deficiency.

In some cases, the Vitamin D 1,25 Dihydroxy Blood Test is ordered if an abnormality associated with the enzyme that converts 25-hydroxyvitamin D to 1,25-dihydroxyvitamin D or kidney disease is suspected. Low levels may be indicative of the latter, as this is often one of the first changes to take place in patients with early kidney failure.

A Vitamin D 25-Hydroxy Blood Test is often ordered to diagnose a vitamin D deficiency.
