The vitamin B2 test, also known as a riboflavin lab test, checks the vitamin B2 blood level.

Vitamin B2, or riboflavin, is one of the B vitamins. Found in foods like vegetables, dairy and supplements, vitamin B2 is important for metabolism in cells. Riboflavin deficiencies are common in underdeveloped countries and can cause inflammation of the mouth (stomatitis), rashes and anemia. High riboflavin levels, or riboflavin toxicity, have not been documented to produce significant side effects.
