What is this test?
This blood test measures the concentrations of vitamin E and carotenoids, which are related fat-soluble nutrients and antioxidants. The lab listing identifies the test as deprecated, so it may not be routinely available.
Why might I need this test?
A clinician may order this test when nutritional status, fat absorption, or use of vitamin supplements is being evaluated. It may also be considered in people with conditions that can affect the absorption of dietary fats, such as some gastrointestinal or liver disorders.
How is the test performed?
A blood sample is collected from a vein, and the serum portion is used to measure vitamin E and carotenoid concentrations. The laboratory reports the results with an interpretation or reference information appropriate for the testing method.
How do I prepare for the test?
Follow the instructions provided by the laboratory or clinician. Some tests may require fasting or a specific collection time, and recent vitamin supplementation can affect results; do not stop supplements unless your clinician advises you to do so.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Low vitamin E or carotenoid concentrations may occur with inadequate intake, malabsorption, or some chronic illnesses. High concentrations may reflect recent supplementation or excessive intake, particularly of fat-soluble vitamins. Results should be interpreted with symptoms, diet, supplement use, and other laboratory findings.
Short name
