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

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.
