This test measures 25-hydroxyvitamin D, the primary circulating form of vitamin D in the blood. It evaluates vitamin D status, essential for bone health, calcium metabolism, and immune function. Deficiency can cause bone disorders like rickets or osteomalacia and increase the risk of osteoporosis and fractures. Low vitamin D is also linked to immune and chronic diseases. Testing is recommended for those with bone pain, muscle weakness, limited sun exposure, or certain medical conditions. No special preparation is needed. Redcliffe Labs provides convenient home sample collection and precise test reports to help maintain optimal vitamin D levels. Read less
