Routine Fecalysis Stool Analysis: Is A Series of Tests Done On A Stool Sample To Help Diagnose Certain Conditions

A routine fecalysis examines a stool sample to diagnose digestive conditions like infection, poor nutrient absorption, or cancer. The test evaluates stool color, consistency, and contents. Abnormal colors can indicate issues like blood, mucus, or parasites. Consistency is also important, with formed stool signaling normal function and watery stool signifying diarrhea. The Bristol Stool Chart further classifies consistency on a scale of 1 to 7 to help identify constipation or diarrhea. Together, analyzing these stool characteristics can provide clues about underlying digestive disorders.
