Vitamin E
A vitamin E test measures the amount of vitamin E in your blood. Vitamin E (also known as tocopherol or alpha-tocopherol) is a nutrient that is found in every cell of your body.

Ranges
Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ
Quest Diagnostics, Micronutrient, Vitamin E 10183
| Population | Interval |
|---|---|
| ≥18 years | 5.7-19.9 mg/L |
| ≥18 years | <4.4 mg/L |
Quest Diagnostics, Micronutrients, Antioxidants Panel 10187
| Population | Interval |
|---|---|
| Coenzyme Q10 (CoQ10) | >35 ug/mL |
| 18-19 years | 26-72 mcg/dL |
| >19 years | 38-98 mcg/dL |
| Male ≥18 years | 0.2-2.1 mg/dL |
| Female ≥18 years | 0.3-2.7 mg/dL |
| Vitamin E, Alpha Tocopherol | ≥18 years | 5.7-19.9 mg/L |
| Vitamin E, Beta-Gamma Tocopherol | ≥18 years | <4.4 mg/L |
Tests
Check the catalog code, specimen, method and preparation for every test that measures Vitamin E. Select up to five tests to compare them side by side.

Micronutrients, Antioxidants Panel 10187
4 analytes · Serum · Fasting required
Quest Diagnostics catalog pageMethod and collection
- Method
- Chromatography • Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS)
- Preparation
- Overnight fasting required. Avoid taking Coenzyme Q10 supplements the morning of the test. Refrain from eating fruits or taking vitamin C supplements 24 hours prior to collection.
- Collection
- Patients should be 18 years of age or greater. Gently invert specimen 5 times (DO NOT SHAKE!), allow to clot for 30-60 minutes at room temperature, centrifuge 10 minutes. Separate serum into 3 amber plastic transport tubes: 1 mL (0.5 mL min) for Vitamin A and E, protect from light, ship frozen (can be refrigerated). 1 mL (0.5 mL min) for Vitamin C, freeze immediately, protect from light, ship frozen. 1 mL (0.5 mL min) for CoQ10, protect from light, ship refrigerated. Do not ship on dry ice. Coenzyme Q10 must NOT be shipped on dry ice. Vitamin C must be shipped on dry ice. Additionally, for remote collection sites, or those with no access to ultra-low freezers or dry ice, it is recommended to schedule patient visits/draws after 12:00 p.m. local time and store the samples at -10° C to -30° C freezers (stable for 8 hours) until picked up by courier. Couriers should then transfer samples to -70° C storage (on dry ice) while enroute to the performing site location.

Verify these ranges and sources
We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
