Vitamin E

Protecting cell membranes from oxidative damage and serving as the most biologically active form for assessing vitamin E status, alpha-tocopherol is the primary analyte measured in clinical practice among the group of fat-soluble compounds comprising vitamin E. Laboratory testing applications include nutritional assessment in patients with malabsorptive conditions, evaluation of suspected vitamin E deficiency presenting with neurological symptoms including ataxia and peripheral neuropathy, monitoring patients receiving total parenteral nutrition, and assessment of premature infants at risk for hemolytic anemia and retinopathy of prematurity. UTAK’s Vitamin A Plus E panels contain vitamin E in lyophilized serum matrix at high and low concentration levels, supporting HPLC and mass spectrometry methods for assay performance monitoring. Stock and custom QC solutions can incorporate related fat-soluble vitamins such as vitamin A and vitamin D, along with other nutritional and endocrinology markers to address your laboratory’s comprehensive micronutrient and clinical chemistry testing requirements.
