VITAMIN D3

The vitamin D3 test measures the level of 25-hydroxyvitamin D3, a precursor of the active form of vitamin D, in the blood. This test is used to diagnose and monitor conditions affecting vitamin D levels, such as vitamin D deficiency, osteoporosis, and certain metabolic disorders. Low vitamin D3 levels can indicate malnutrition, inadequate sun exposure, or malabsorption. The vitamin D3 test provides valuable information for assessing nutritional status, diagnosing underlying conditions, and guiding treatment decisions to manage vitamin D levels effectively.
