The Vitamin D, 25-OH, Total test measures the total level of 25-hydroxyvitamin D in the blood, the primary circulating form of vitamin D and the best indicator of overall vitamin D status. Vitamin D is essential for bone health, calcium absorption, immune function, and muscle strength.
This test is commonly used to evaluate vitamin D deficiency or insufficiency, monitor supplementation, and assess bone and metabolic health. Abnormal vitamin D levels may be associated with bone disorders, muscle weakness, immune dysfunction, or increased risk of certain chronic conditions. Results are interpreted alongside calcium and other related markers for comprehensive assessment.
