Vitamin E (Tocopherol) is a blood test that measures the level of vitamin E, a fat-soluble antioxidant that helps protect cells from oxidative damage and supports immune, nerve, and muscle function. The test is needed to evaluate suspected vitamin E deficiency or excess, particularly in people with fat-malabsorption disorders, certain liver or gastrointestinal conditions, or nutritional deficiencies, and can help guide appropriate clinical management.
Vitamin E is a fat-soluble antioxidant that helps protect cells from oxidative damage and supports normal immune, nerve, muscle, and other cellular functions.
Tocopherol is a group of compounds with vitamin E activity. Alpha-tocopherol is the form most commonly measured when assessing vitamin E status in blood.
A low level may indicate vitamin E deficiency, which can occur due to inadequate intake or impaired absorption of dietary fats and fat-soluble vitamins.
Risk is increased in people with conditions that impair fat absorption, certain gastrointestinal or liver disorders, some inherited conditions, and prolonged inadequate nutritional intake.
