Fecal pH test

A fecal pH test is one where a specimen of feces is tested for acidity in order to diagnose a medical condition. The pH of human feces is variable but usually alkaline. An acidic stool can indicate a digestive problem such as lactose intolerance, an infection such as E. coli or rotavirus, or overgrowth of acid-producing bacteria (such as lactic acid bacteria).
