Selenium

Critical cofactor functions for selenoproteins including glutathione peroxidases and thioredoxin reductases make selenium an essential trace element. Laboratory monitoring of selenium is performed in nutritional assessment of patients receiving total parenteral nutrition or with malabsorptive conditions, evaluation of selenium deficiency states associated with cardiomyopathy (Keshan disease) and skeletal myopathy, occupational exposure monitoring in electronics and glass manufacturing industries, and environmental exposure evaluation. UTAK’s Metals, Trace Elements, and Urine Metals panels contain selenium in lyophilized serum, whole blood, and urine matrices at multiple concentration levels, supporting ICP-MS methods for assay performance monitoring. Stock and custom QC solutions can incorporate related trace elements such as zinc, copper, manganese, chromium, and other essential and toxic metals to address your laboratory’s comprehensive nutritional assessment and trace element testing requirements.
