The vitamin D blood test measures the level of vitamin D in your blood. It is ordered to check for deficiency, which can affect bone health, and to monitor treatment.

What it measures

  • 25-hydroxyvitamin D — The main form of vitamin D in the blood; used to assess overall vitamin D status.
  • 1,25-dihydroxyvitamin D — The active form; measured less often, usually for specific medical conditions.
  • Calcium — Often checked alongside vitamin D because vitamin D helps regulate calcium levels.
  • Phosphate — Sometimes measured because vitamin D affects phosphate balance.
  • Alkaline phosphatase — A bone enzyme that may be checked if bone health is a concern.

Who it is for

A clinician may order this test if you have symptoms of deficiency, such as bone pain or muscle weakness, or if you have conditions that affect vitamin D absorption. It is also used to monitor vitamin D levels during treatment.
