In short

Vitamin E is a fat-soluble vitamin that works as an antioxidant, helping protect cell membranes from damage. The main form in the body is alpha-tocopherol, which is what blood tests usually measure.

Because it is fat-soluble, vitamin E is absorbed alongside dietary fat and stored in the body's fatty tissue and liver.

Why test this?

Vitamin E protects cells from oxidative damage and supports immune and nerve function. Deficiency is rare and mostly seen with fat malabsorption or certain genetic conditions, where it can cause nerve and muscle problems over time.

Testing is helpful when malabsorption is suspected or when assessing nutritional status. Because vitamin E travels with blood fats, results are often interpreted in relation to blood lipid levels.

What is a normal result?

Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.

Your Aniva report reads your result against these values together with your age, sex and the rest of your panel.

Ranges are guidance and vary by lab and assay, aligned with DGKL practice. Always read your result against your own lab's reference interval.

What insights will this test give you?

You learn whether your vitamin E level is low, adequate, or high. True deficiency is uncommon and usually relates to conditions that impair fat absorption. A low result in that context can support a diagnosis, while a high result usually reflects supplementation.

What can affect this result?

What can skew the result

Blood fat levels affect vitamin E results, so high or low lipids can shift the value independently of vitamin E stores. Recent supplementation raises levels. Conditions that impair fat absorption lower them.

Best interpreted with

Read alongside total cholesterol and triglycerides, since vitamin E is transported with blood lipids and is often expressed relative to them.
