Resource Summary

Clinical Question:
In adults^ what is the evidence to test serum vitamin D levels?

Bottom Line:
Routine testing of vitamin D levels is unnecessary. Laboratories often report serum levels between 50 and 75–80 nmol/L as insufficient but this is not supported by consistent or reliable evidence. Additionally^ large variability in the test limits interpretation of repeat measurements.
