Calcium, Vitamin D, and Supplementation
Apr 24, 2011
I have followed the increasing focus on Vitamin D serum levels as possibly protective for a variety of pathologies including decreases in bone density. However my current labs indicate only Calcium levels (around 9.5 mg/dL) as within normal range.
What is the accepted normal range for Vitamin D and when (if ever) is this typically tested for patients with HIV? What is the current medical opinion on supplementation? Never unless there is concern about lab results? clinical pathology(ies)? Up to the patient within established limits?
To what extent does the calcium serum level indicate the need for Vitamin D testing or can function as a predictor of Vitamin D levels?
Response from Dr. Holodniy
The normal range for 25-hydroxy vitamin D is between 30.0 to 74.0 ng/mL. Many people with HIV infection are deficient in vitamin D and therefore supplementation is a good idea. Vitamin D is not only important in calcium and bone metabolism, but for good immune system function. It is more than appropriate to have the level checked with HIV infection. Many people with HIV infection and normal calcium levels have low vitamin D levels.
