Vitamin B2 blood test

A vitamin B2 (riboflavin) blood test measures the levels of riboflavin in the blood. Riboflavin is a nutrient that is important for the metabolism of carbohydrates, proteins, and fats. It is also necessary for the proper function of the skin, eyes, and nervous system. Riboflavin is found in a wide variety of foods, including meat, dairy products, vegetables, and grains, and is also available as a dietary supplement.

The results of a vitamin B2 blood test can help a healthcare provider diagnose and monitor conditions related to riboflavin levels, such as riboflavin deficiency or excess, liver problems, and malnutrition. The test can also be used to monitor the effectiveness of riboflavin supplementation. Riboflavin deficiency can cause a wide range of symptoms, including skin rashes, eye problems, and mouth sores. It is important to treat riboflavin deficiency promptly to prevent these complications.
