Vitamin D Testing Overview

D testing is a medical procedure used to measure vitamin D levels in a person’s blood. Vitamin D, a significant nutrient, is noteworthy in maintaining bone health, supporting the immune system, and promoting overall well-being. The test focuses on the two primary shapes of vitamin D in the blood: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). The 25-hydroxyvitamin D test, known as the 25(OH)D test, is the most common method to assess vitamin D levels. It gives an overall picture of a person’s vitamin D status by measuring both forms. Healthcare providers ordinarily order this test for different reasons, such as diagnosing deficiency or insufficiency, checking supplementation, evaluating certain medical conditions related to vitamin D, or evaluating health in specific populations at hazard. The test results are detailed in nanograms per milliliter (ng/mL) or nanomoles per liter (nmol/L), with the optimal range falling between 20-50 ng/mL (50-125 nmol/L) for most individuals.
