Vitamin B2, Whole Blood

This test measures the amount of vitamin B2, also known as riboflavin, in your blood. Your body needs this nutrient to convert food into energy and keep your skin and blood cells healthy. This test helps determine if you have a vitamin deficiency that could explain symptoms like fatigue, mouth sores, or skin issues. While it confirms whether your levels are low, it does not identify the specific underlying cause of the deficiency by itself.
