This blood test evaluates vitamin E levels to check for deficiency. Vitamin E is a fat-soluble vitamin and antioxidant that helps protect cells from damage. The test may be ordered when a provider suspects a deficiency in people with conditions that impair fat absorption, such as chronic cholestasis, or in individuals receiving long-term intravenous nutrition. It may also be considered when neuromuscular symptoms are being evaluated. Because vitamin E is fat-soluble and stored in the body, results are interpreted with your diet, medical history, and other tests.

• Vitamin E (alpha-tocopherol) Measures the level of this fat-soluble vitamin in the blood.
• Lipid panel Sometimes measured because vitamin E travels with blood lipids, which helps interpretation.

• People with chronic cholestasis or fat malabsorption
• Individuals receiving long-term intravenous nutrition
• People with neuromuscular symptoms being evaluated
• Those with very restricted diets or malnutrition

• Fasting is often requested before the draw.
• Tell the collector about vitamin E supplements you take.
• Follow any instructions provided for your specific panel.

A low vitamin E level may suggest deficiency, which can relate to fat malabsorption, cholestasis, or prolonged poor nutrition, while high levels usually reflect supplements. Because vitamin E travels with blood lipids, a provider may interpret the result alongside a lipid panel. Discuss results with a healthcare provider before making any changes.
