Vitamin D, also known as calciferol, is a fat-soluble vitamin that has a variety of physiologic effects, most prominently in calcium homeostasis and bone metabolism. Providers are reminded that there should be a direct medical need or indication for testing of vitamin D serum levels. Therefore, routine testing for vitamin D deficiency in healthy adults and children is not indicated according to evidence-based reviews or clinical practice guidelines from organizations that include, but are not limited to, the U.S. Preventive Services Task Force, the American College of Obstetrics and Gynecology, the American Society of Clinical Pathology, and the Endocrine Society.

Vitamin D testing should primarily be reserved for:

• individuals with signs and symptoms of vitamin D deficiency or toxicity;
• asymptomatic individuals at increased risk for vitamin D deficiency.

Individuals at increased risk for vitamin D deficiency may include those with osteoporosis, chronic kidney disease of at least stage 3, and parathyroid disorders.

When clinically appropriate, AmeriHealth-participating laboratories are capable of performing vitamin D testing. If you have any questions about participating laboratories, please contact your Provider Partnership Associate or your Network Coordinator.
