What it measures

  • 25-dihydroxyvitamin D (calcitriol) — The active hormone form of vitamin D that helps control calcium and phosphate levels.
  • Calcium — A mineral that works closely with vitamin D and parathyroid hormone.
  • Phosphorus — Another mineral affected by vitamin D activity.
  • Parathyroid hormone (PTH) — A hormone that rises or falls in response to calcium and vitamin D levels.

Preparation

No fasting is usually required. Tell your clinician about any vitamin D, calcium, or steroid supplements you take, because timing and recent doses can affect the result.

Results and what they mean

Results are reported as a number with a reference range, and your clinician interprets them alongside calcium, phosphorus, and PTH. A single value is rarely enough to make a decision. This is general information only and is not medical advice; discuss your results with a qualified clinician.

Frequently asked questions

How is this different from a regular vitamin D test?

A regular vitamin D test measures 25-hydroxyvitamin D, the storage form. This test measures calcitriol, the active hormone form, which is used in more specific situations.

Do I need to stop my vitamin D supplement?

Ask your clinician. Do not stop or change any supplement or medication on your own before testing.

Can I eat before this test?

Yes, fasting is usually not required unless your clinician gives other instructions.

What if my result is outside the reference range?

Your clinician will consider your symptoms, other lab values, and medications before deciding what it means. Do not adjust treatment based on the number alone.
