This test measures the bioactive form of vitamin D. It is used in the differential diagnosis of hypocalcemia and to monitor patients with renal osteodystrophy or chronic renal failure. This test is not suitable for diagnosis of vitamin D deficiency and monitoring monitoring supplementation in most patients. The 25-hydroxyvitamin D test is the recommended test for those purposes (N Engl J Med. 2007;357:266-281).

Collect blood in a non-gel barrier red-top tube. Allow blood to
clot (30 minutes) at room temperature. Centrifuge and separate
the serum from the cells. Note: If sample is submitted with less than
1.1 mL and needs to be repeated, the sample will be canceled with
the comment TNP-Initial testing necessitated a repeat, but there was
insufficient sample to perform repeat.
