About This Topic

Vitamin D tests may be misordered because two closely related tests with similar names are available:

Vitamin D, 1, 25-Dihydroxy (0080385) is not recommended for assessing vitamin D status except in certain circumstances (eg, renal insufficiency).
Vitamin D, 25-Hydroxy (0080379) is recommended for assessing vitamin D status in individuals at risk for vitamin D deficiency.

Recommendation

Clarification of the utility of Vitamin D, 25-Hydroxy versus D 1,25-Dihydroxy testing may be beneficial. Vitamin D, 25-Hydroxy (0080379) is the preferred test to diagnose vitamin D insufficiency and monitor response to supplementation.
