What your results can mean
Reading your report
Normal ranges differ between labs, so compare your result with the range printed on your report and discuss it with your doctor.
If the result is outside the usual range
A low level can be seen with fat absorption problems such as cystic fibrosis, long-term liver or pancreas disease, or rare inherited conditions, and can affect nerves and muscles. A high level is usually seen with supplements and can raise bleeding risk in people on blood thinners.
Who usually has this test
People with fat absorption problems, unexplained nerve or balance problems, premature babies, and those taking high-dose vitamin E.
Risks and aftercare

Questions about this test
Why might my lipid levels affect the vitamin E result?
Vitamin E travels in the blood with fats, so high cholesterol or triglycerides can make vitamin E look higher. Some labs report it as a ratio with blood fats.
Does vitamin E help fertility?
Vitamin E is an antioxidant and is sometimes included in fertility supplements, but evidence that it improves pregnancy rates is limited. Ask your doctor before taking high doses.
What are signs of vitamin E deficiency?
Deficiency is rare but can cause weakness, poor balance, numbness and vision problems. It is usually linked with conditions that affect fat absorption.
