Quick answer
The vitamin B2 test measures riboflavin, a water-soluble vitamin involved in energy production. Riboflavin works with other B vitamins to help cells use carbohydrates, fats, and proteins. It also supports the health of skin, eyes, and the lining of the mouth and throat. The test uses a blood sample and is ordered when a deficiency is suspected or when nutrition needs review.
What this test measures
Riboflavin, or vitamin B2, is a building block for two important coenzymes, FAD and FMN, that drive many reactions in energy metabolism. It also helps regenerate other nutrients, including certain forms of vitamin B. Because the body cannot store much of it, a regular dietary supply is needed.
Testing may measure plasma or serum riboflavin or, more often, the activity of an enzyme that depends on it. One common approach is the erythrocyte glutathione reductase activity coefficient, which rises when riboflavin status is poor. The test requires only a blood sample.
Deficiency is uncommon in people eating a varied diet, since riboflavin is found in dairy, eggs, lean meats, and many fortified foods. It can appear with poor intake, malabsorption, or increased needs. Symptoms may include cracked lips, a sore tongue or throat, and skin irritation, though these signs overlap with other conditions.
