Who should test?

  • Vitamin D is clinically useful to diagnose disorders related
  • to intestinal malabsorption and vitamin D deficiency or
  • intoxication. The 25-Hydroxy vitamin D blood test allows
  • monitoring for therapeutic response in patients being
  • treated for vitamin D-related disorders.

The body gets vitamin D from two sources: dietary intake through foods and supplements (exogenous), and through production in the skin upon exposure to sunlight (endogenous). Although vitamin D is found naturally in only a few foods, in the United States, many products are supplemented with it, including milk, breakfast cereals and juices. Those at risk of vitamin D deficiency include individuals who are elderly; obese; have dark skin; are institutionalized, home bound or have limited sun exposure; have undergone gastric bypass surgery; and have conditions such as cystic fibrosis and Crohn's disease that interfere with fat absorption.
