A vitamin E test measures the amount of vitamin E in your blood. It is ordered when a doctor suspects a deficiency or, less commonly, too much vitamin E, often due to malabsorption or prolonged high-dose supplements.
What it measures
- Alpha-tocopherol — The main active form of vitamin E in the body.
- Gamma-tocopherol — Another form of vitamin E, sometimes measured to assess overall status.
- Total vitamin E — A combined measure of all vitamin E forms.
- Lipid panel (cholesterol, triglycerides) — Often checked alongside vitamin E because levels are influenced by blood fats.
Who it is for
Doctors typically order this test for people with symptoms of deficiency, such as nerve problems or muscle weakness, or for those with conditions that impair fat absorption, like cystic fibrosis or celiac disease.
Preparation
Fasting for 8–12 hours is often recommended, but your doctor will give specific instructions. No other special preparation is usually needed.
Results and what they mean
Results are reported as a number, often in milligrams per liter (mg/L) or micrograms per milliliter (mcg/mL), and compared to a reference range. A clinician interprets the result in the context of your health, diet, and other tests. This information is not medical advice; discuss your results with your healthcare provider.
