Why 25-Hydroxy Vitamin D Test?

Vitamin D is one of the water-soluble vitamins that is required for the healthy formation and maintenance of teeth and bones. It is made in the body when exposed to sunlight, but can also be supplemented in the diet.

There are two major forms of the vitamin, 1,25 dihydroxyvitamin D and 25 hydroxyvitamin D. 25 hydroxyvitamin D is the inactive form of the vitamin which is converted by the liver and kidney into the active form. This is the form which is frequently measured, because of the higher amounts in the body and the long half-life. It gives an indication of the vitamin D status of an individual.
