A Vitamin B2 test measures the amount of riboflavin (vitamin B2) in your blood. It is usually ordered when a doctor suspects a deficiency, which can cause symptoms like fatigue, cracked lips, or sore throat, or to monitor certain health conditions.
What it measures
- Vitamin B2 (riboflavin) — The main nutrient being measured.
- Erythrocyte glutathione reductase activity — An enzyme test that reflects how well B2 is working in your red blood cells.
- Erythrocyte glutathione reductase activation coefficient (EGRac) — A calculated ratio that helps assess B2 status more accurately.
Who it is for
Doctors typically order this test for people with signs of vitamin deficiency, poor diet, malabsorption conditions, or those taking certain medications that affect B2 levels.
Preparation
No fasting is usually required. Tell your doctor about all medications and supplements you take, as some can affect the results.
Results and what they mean
Results are reported as a number or range for each marker, and your doctor will interpret them based on your health history and other tests. A low result may suggest deficiency, but only a clinician can determine what it means for you. This is general information, not medical advice.
