Vitamin D Testing
January 13, 2021- A systems-based project to reduce the overuse of inappropriate Vitamin D testing has been approved with the input and review of McLaren physician leaders on the Lab Formulary Task Force and McLaren Steering Committee.
WHY: Vitamin D deficiency is common in many populations, particularly in patients at higher latitudes, during winter months and in those with limited sun exposure. Over the counter Vitamin D supplements and increased summer sun exposure are sufficient for most otherwise healthy patients. Laboratory testing for Vitamin D levels with 25-OH testing is appropriate only in higher risk patients when results will be used to institute more aggressive therapy (e.g., osteoporosis, chronic kidney disease, malabsorption, some infections, obese individuals).
WHAT: Implement a systems-based project to reduce inappropriate vitamin D testing. Project goals are to support appropriate use of lab resources, decrease inappropriate use of vitamin D tests, standardize laboratory policies, and improve lab stewardship.
