The Vitamin E (Tocopherol) assay is a laboratory test used to measure the concentration of vitamin E in the blood. Vitamin E is a fat-soluble antioxidant that protects cells from oxidative damage, supports immune function, and is essential for skin, eye, and neurological health.

This test is commonly performed to:

• Assess nutritional status of vitamin E
• Diagnose vitamin E deficiency or excess
• Monitor patients with malabsorption disorders, liver disease, or certain genetic conditions affecting vitamin E metabolism
