What is a vitamin E (tocopherol) test?
A vitamin E test measures the amount of vitamin E in your blood. Vitamin E (also known as tocopherol or alpha-tocopherol) is a nutrient that is important for many body processes. It helps your nerves and muscles work well, prevents blood clots, and boosts the immune system. Vitamin E is a type of antioxidant, a substance that protects cells from damage.
Most people get the right amount of vitamin E from their diet. Vitamin E is found naturally in many foods, including green, leafy vegetables, nuts, seeds, and vegetable oils. If you have too little or too much vitamin E in your body, it can cause serious health problems.
Other names: tocopherol test, alpha-tocopherol test, vitamin E, serum
