Vitamin D, 25-Hydroxy (Quest Diagnostics)

Quest Price: $69.99

The Vitamin D, 25-Hydroxy test is primarily ordered to measure the amount of 25-hydroxy vitamin in the bloodstream to rule out Vitamin D deficiency.
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 hypercalcemia. This assay employs liquid chromatography tandem mass spectrometry to independently measure and report the two common forms of 25-hydroxy vitamin D: 25OH D3 - the endogenous form of the vitamin and 25OH D2 - the analog form used to treat 25OH Vitamin D3 deficiency.

A significant deviation from the normal range may require further evaluation by your physician.
