Calcidiol & Calciferol & Calcitriol panel
Measures three forms of vitamin D to comprehensively assess vitamin D status and metabolism.
Why This Biomarker Matters
Vitamin D is critical for bone health, calcium absorption, and immune function. Low levels increase risk of osteoporosis, infections, and depression.
Overview
This comprehensive vitamin D panel measures three forms: 25-hydroxyvitamin D (the storage form that indicates overall status), vitamin D2 (from dietary sources), and 1,25-dihydroxyvitamin D3 (the active form). Together, these tests assess vitamin D metabolism and availability. Vitamin D is essential for calcium absorption, bone health, immune function, and mood. Deficiency is linked to weak bones, increased infection risk, and depression.
