Vitamin D testing on the rise again

The rise suggests some doctors are doing 'unnecessary' tests, say the researchers in the MJA

The rate of vitamin D testing is creeping back up again, despite measures taken six years ago to reduce the ordering of tests by doctors.

But the patients who need it the most are missing out, an Medical Journal of Australia study reveals.

Medicare data shows the rate for vitamin D deficiency testing rose 34% between 2015 and 2019.

The marked increase was not explained by changes in clinical or demographic factors, “suggesting that at least some screening is unnecessary”, the authors said.
