Vitamin D is one of the important vitamins our bodies need to be healthy. It promotes healthy bone growth and can reduce inflammation, according to the National Institutes of Health*. 

It occurs naturally in some foods and is added to others such as milk and is available as a dietary supplement. You can also get vitamin D naturally from the sun. 

Low levels of vitamin D can increase the risk of broken bones. It can also be a factor in other health conditions. For these reasons, many doctors will order tests to measure vitamin D. 

In generally healthy people, a vitamin D deficiency can be treated with an over-the-counter supplement. The testing is unnecessary, says Dr. Lloyd Kapp, a medical director with BlueChoice® HealthPlan. This is why doctors do not generally recommend testing for vitamin D deficiencies**.

If you are high risk, get the test, Kapp says. If not, ask your doctor if you can boost your vitamin D with sun exposure, food and supplements before having the test. 

“In general, healthy people don’t need to be tested for vitamin D deficiency. Everyone can take vitamin D supplements, get safe amounts of limited sun exposure, and they should have adequate vitamin D levels in their systems,” Kapp says. 

Even if you are at risk for other diseases, like Type 2 diabetes, a vitamin D test usually isn’t helpful, according to Choosing Wisely*.

The tests are typically ordered routinely as a part of a general screening. But these tests can lead to extra treatment and extra costs. Patients should know that these tests are not free. 

Up to 90 percent of vitamin D tests may be clinically useless, according to a report in the Journal of the American Medical Association*. This means that the findings were not necessary to guide care. 

In South Carolina, based on extrapolated claims data 39 percent of vitamin D tests in 2017 were likely unnecessary. 

Individuals with kidney disease, osteoporosis or other health conditions may need to have a vitamin D test as they are considered higher risk for vitamin D issues. A list of high-risk conditions or concerns can be found here. Patients should talk with their doctor about their individual risks. 

If your doctor orders a vitamin D test, ask why, Kapp recommends. 

“Bring it up and discuss it with your doctor. Is it necessary?” he says. “This doesn’t mean that you never need a vitamin D test. It just means that you should take a thoughtful approach to your own health care overall and fully discuss your care with your doctor.”
