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
To evaluate vitamin E deficiency and excess and to monitor its absorption.
To screen premature babies who are at higher risk of vitamin E deficiency.
Testing is needed if symptoms of vitamin E deficiency (e.g. muscle weakness, slow reflexes, difficulty or unsteady walking, vision problems) or of vitamin E excess are present. Vitamin E levels may reveal the way your body is digesting and using nutrients, indicating certain disorders if levels are too high or low.
