About the Test

This vitamin D test measures the amount of 25-hydroxyvitamin D in your blood. Your body absorbs vitamin D when exposed to sunlight or consuming fortified foods – storing it in fat cells until needed for use. Your liver and kidneys convert this inactive vitamin D to 25-hydroxyvitamin D, the active form the body needs. Vitamin D deficiency can indicate bone disease, nutrition disorders, or other metabolic complications.
