Vitamin D, 25-hydroxy Blood Test

Use:
The Vitamin D 25-Hydroxy is used to rule out Vitamin D deficiency. Your body absorbs Vitamin D through exposure to sunlight, as well as through consumption of plants, foods and supplements.

Vitamin D plays an important role in the maintenance of organ systems. It regulates the calcium and phosphorus levels in the blood by promoting their absorption from food in the intestines and by promoting re-absorption of calcium in the kidneys. Vitamin D also promotes bone formation and mineralization and is essential in the development of an intact and strong skeleton. It also inhibits parathyroid hormone secretion from the parathyroid gland.

Low levels of Vitamin D can put you at higher risk for coronary artery disease, stroke, diabetes and peripheral arterial disease.

Recommended For:
Those who have issues related to bone metabolism or parathyroid function, possible Vitamin D deficiency or malabsorption, and to monitor some patients taking Vitamin D.

Special Notes:
No special preparation is necessary prior to blood sample collection.
