Selenium is a tiny but important nutrient your body needs. It helps your body create special proteins. These proteins act like tiny shields. They protect your cells from harm.
Doctors might check your selenium levels to see if your body has the right amount. They do this if they think you might have too little or too much selenium. They also check levels for people who get their food through a tube for a long time.
Reference ranges for selenium can vary by laboratory, and interpretation may depend on age, sex, pregnancy status, and clinical context.
