Vitamin A

Retinol (vitamin A) is a critical fat-soluble vitamin biomarker measured in nutritional assessment, evaluation of vitamin A deficiency and hypervitaminosis A toxicity, and monitoring patients receiving total parenteral nutrition or with liver disease. UTAK’s Vitamin A Plus E panels contain vitamin A 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 E and vitamin D, along with other nutritional and endocrinology markers to address your laboratory’s comprehensive micronutrient and clinical chemistry testing requirements.
