Vitamin D deficiency a poor marker of bone disease

Serum vitamin D testing is labelling patients at risk of bone disease without robust evidence to back the cut-offs, according to a provocative claim by leading Australian endocrinologist Professor Ego Seeman.

In an unpublished study presented at a conference last week, Professor Seeman, from Austin Health in Melbourne, found that vitamin D deficiency was only rarely associated with markers of bone disease, and vitamin D insufficiency not at all.
