Diagnostic & Screening Tests
The material produced by a bowel movement is commonly referred to as feces or stool. A stool sample may be tested for a variety of abnormalities, such as white blood cells, which are not normally found in stool. The presence of white blood cells in stool is a sign of colon inflammation, infection, or both. This can be caused by things like inflammatory bowel disease, bacteria, viruses, or parasites.
