Vitamin D Test

This test measures the level of vitamin D in the blood.

This test measures the level of vitamin D in the blood.

This test checks the level of vitamin D in your blood. Vitamin D helps the body absorb calcium and is important for bone health. Vitamin D may also have a number of other effects on your health.

  • Most of us get some of our vitamin D from exposure to sunlight. Some other sources of vitamin D include foods that have vitamin D added (i.e., milk) and vitamin supplements.
  • However, many people have levels of vitamin D that are lower than they should be.
  • Your healthcare provider may order this test to find out if you have a healthy level of vitamin D or if you need to take supplements.

In an adult, the blood sample is usually taken by placing a needle in a vein in the arm or by pricking a finger. In a baby or child, the sample may be taken by pricking a finger or heel.

  • No special preparation is needed.
  • Ask your healthcare provider if you need to stop taking any medicines before the test. Do not stop taking any medicine unless your healthcare provider tells you to do so.
  • This care path's costs do not include the charge to draw blood from a vein (venipuncture).
  • There will only be one charge to draw blood, even if multiple tests are being performed on the samples that are taken.

What should I ask my healthcare provider before having this test?

  • What is the reason for the test? Will the test results change my treatment plan? If not, do I need the test?
  • Are there concerns with the use and accuracy of this test?
