Metals: Selenium




Chemical Pathology - Routine Laboratory

Clinical indications

Selenium is present at the active site of glutathione peroxidise, which in vivo catalyses the destruction of hydrogen peroxide and organic hydroperoxides. In this role, it forms together with vitamin E and superoxide dismutase, part of cellular anti-oxidative capacity. More recently, selenium was shown to be an essential component of type I iodothyronine 5’deoidinase, which converts thyroxine (T4) to the more biologically active hormone 3,5,3’-triodothyronine (T3)
