Eosinophil Protein X is a water-soluble protein that is found in eosinophils. Fecal Eosinophil Protein X levels are abnormally increased in people with intestinal inflammation where high concentrations of eosinophils may be found. Eosinophils proliferate and accumulate in areas of inflammation. When they degranulate, they release their contents including Eosinophil Protein X. Thus, Eosinophil Protein X levels in stool are a marker of eosinophil activity in the gastrointestinal system. The test may help people with inflammatory bowel disease determine if they are in a period of remission (low levels) or if they are about to have a relapse (increasing levels).
Normal Ranges for Eosinophil Protein X:
