Vitamin B2 (Riboflavin) Test

The Vitamin B2 (Riboflavin) test is a blood test that measures the levels of riboflavin in the body. Riboflavin is a water-soluble vitamin that is essential for overall health, including energy production, metabolism, and the maintenance of healthy skin and eyes.

Low levels of riboflavin can lead to symptoms such as fatigue, weakness, sore throat, and inflammation of the mouth and tongue. On the other hand, high levels of riboflavin are not common, as excess riboflavin is usually excreted in the urine.

To perform the test, a blood sample is drawn from a vein in your arm. It is important to follow any fasting instructions provided by your test provider before the test. The results of the test will indicate whether your riboflavin levels are within the normal range.

If your riboflavin levels are found to be low, your healthcare provider may recommend dietary changes or riboflavin supplements to increase your intake of the vitamin.
