Vitamin A (Retinol) (Quest Diagnostics)
Vitamin A is needed for growth and for strong bones and teeth. As you grow older, it helps keep your skin and eyes healthy. Vitamin A is present in liver, fish liver oils, dairy products, dark green and yellow-orange vegetables, and in fruits. Too much vitamin A may cause symptoms that include headache, itchy skin, and hair loss.
A significant deviation from the normal range may require further evaluation by your physician.
Estimated turnaround for results is 5 business days.

Vitamin D, 25-Hydroxy LC/MS/MS (Quest Diagnostics)
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.

Vitamin B12 and Folates (Quest Diagnostics)
Folic acid deficiency is common in pregnant women, alcoholics, patients with diets that do not include raw fruits and vegetables, and people with structural damage to the small intestine. The most reliable and direct method of diagnosing folate deficiency is the determination of folate levels in both erythrocytes and serum. Low folic acid levels, however, can also be the result of a primary Vitamin B12 deficiency that decreases the ability of cells to take up folic acid. Vitamin B12 is decreased in pernicious anemia, total or partial gastrectomy, malabsorption and certain congenital biochemical disorders.
Significant deviations from the normal range may require further evaluation by your physician.
