Vitamin E (Tocopherol)

This test measures the level of vitamin E (tocopherol) in your blood, giving a clear picture of your body's antioxidant status. Vitamin E is a fat-soluble vitamin that protects your cells from oxidative stress, supports immune function, and helps keep your blood vessels and skin healthy. It is particularly useful if you have symptoms of deficiency such as muscle weakness, vision problems, or numbness, or if you have a condition that affects fat absorption, such as cystic fibrosis, coeliac disease, or chronic pancreatitis. It may also be requested if you follow a very low-fat diet or have a family history of vitamin E deficiency.

The test is performed on a simple blood sample using a validated analytical method, typically high-performance liquid chromatography (HPLC) or liquid chromatography-tandem mass spectrometry (LC-MS/MS), which accurately quantifies tocopherol levels.

Why it matters
Vitamin E deficiency can lead to nerve damage, muscle weakness, and anaemia, while excess levels may interfere with blood clotting. Measuring your vitamin E level helps your doctor identify whether your symptoms are related to a deficiency or toxicity, guide appropriate supplementation, and monitor conditions that affect fat absorption. Early detection and management can prevent long-term complications and support your overall health.
