About this test
A blood test designed to evaluate vitamin D level.
Vitamin D is important for bone health, calcium absorption, muscle function, and immune-related processes. Testing may be useful for people with limited sun exposure, low dietary intake, darker skin pigmentation, malabsorption concerns, osteoporosis/osteopenia risk, fatigue, muscle aches, or patients taking vitamin D supplements. Mayo Clinic notes that vitamin D helps the body absorb calcium and supports bone health, muscle function, and immune health. :contentReference[oaicite:3]{index=3}
