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, Independence?s participating laboratories are
capable of performing vitamin D testing. If you have any questions about
participating laboratories, please contact your Network Coordinator.
