What this test is

This blood test checks the level of vitamin E, a fat-soluble nutrient important for nerve and muscle function. It is used to evaluate deficiency in people with chronic cholestasis, neuromuscular disease, or those receiving parenteral nutrition.

What it measures

  • Vitamin E (alpha-tocopherol) — reflects the amount of this nutrient in the blood
  • Lipid profile (sometimes) — helps interpret vitamin E levels relative to cholesterol

What the test involves

A healthcare professional collects a small sample of blood, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test if you have a condition that affects how your body absorbs fats or if you have symptoms that could be related to low vitamin E. It helps determine whether your vitamin E level is lower than expected.

Preparation

Your lab will give you specific instructions to follow before the test. These may include fasting or avoiding certain supplements, so always check with the collection lab.

How results are reported

Results are reported as a number that your clinician will interpret. Reference ranges vary by laboratory, so your result should be compared to the range provided by the lab that performed the test.
