    Test Description

    Vitamin B2, (Riboflavin)

    Vitamin B2 is also known as riboflavin. Riboflavin is essential in energy production as FAD. It is important in the synthesis and breakdown of fats. It activates the vitamins B6 and folic acid. It is also important in the synthesis of corticosteriods, red blood cells and glycogen. It is found in Brewer's yeast, liver, meat, broccoli, dairy products, wheat germ, poultry, and whole grain products.

    A deficiency of riboflavin is associated with skin problems especially around the nose, mouth, and ears. In addition, a patient may have a "smooth tongue," redness, burning and excessive tearing of the eyes, light sensitivity, anemia, personality changes and cataracts. The RDA for riboflavin is 1.3 mg. A supplemental level is suggested as 1.7 to 50 mgs. There is no toxic dose listed for riboflavin.

    Specimen is 2.0 mL of washed heparinized RBCs. Collect the sample in a heparin tube. Centrifuge the tube, then wash the RBCs one time with normal saline. Protect from light and ship in amber plastic tube.
