Back to Test Directory0286 : Vitamin D, 25-Hydroxy, Serum
INFORMATION:
Alternate Name:
CALCIFEDIOL
Methodology:
Chemiluminescence
Clinical Utility:
Measurement of serum 25-OH vitamin D concentrations provide a good index of circulating vitamin D activity in patients not suffering from renal disease. Lower than normal 25-OH vitamin D levels can result from a dietary deficiency, poor absorption of the vitamin or impaired metabolism of the sterol in the liver. A 25-OH vitamin D deficiency can lead to bone diseases such as rickets and osteomalacia. Above normal levels can lead to hypercalcemia.
