Vitamin E (Tocopherol) Test Test
A vitamin E test measures the amount of vitamin E in your blood. It helps check if you have enough vitamin E for your nerves, muscles, immune system, and to prevent blood clots. Too little or too much vitamin E can cause health problems.
What this test measures
A vitamin E test measures the amount of vitamin E (also known as tocopherol or alpha-tocopherol) in your blood. Vitamin E is a nutrient found in every cell that helps nerves and muscles work, prevents blood clots, and boosts the immune system.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
Higher-than-normal results
High vitamin E levels mean you are getting too much vitamin E. If you have been taking vitamin E supplements, you will need to stop. If bleeding problems occur, your provider may prescribe medicines.
Lower-than-normal results
Low vitamin E levels mean you are not getting or absorbing enough vitamin E. Your provider will use your medical history and other tests to find the cause. Treatment usually involves vitamin supplements and treating any absorption problems.
