Antioxidants - Glutathione Peroxidase (Ransel)

Selenium is an essential trace element, involved in the aetiology of a number of diseases. At normal concentrations, selenium has a protective effect against several disease states however this protection is lost at lower concentrations and selenium can be toxic at high concentrations. It is therefore important to monitor selenium levels to ensure they are kept within the normal range. Ransel measures Glutathione Peroxidase which has a direct correlation with selenium levels.
