This test is used to measure Vitamin D levels in the blood. The Vitamin D 25-Dihydroxy test measures the active form of Vitamin D which is produced in the liver and kidneys through the conversion of Vitamin D 25-Hydroxy. This test is not typically used as a routine measurement to assess if a person has a vitamin D deficiency because it may show normal results even if a person has an overall deficiency. It is more useful when a person is suspected of having a condition that is producing an excess of vitamin D such as Sarcoidosis or certain types of Lymphoma. This test may also be ordered to aid in the diagnosis of Parathyroid disorder or kidney failure.

No special preparation required.
