Stool guaiac is a diagnostic test used to detect the presence of hidden (occult) blood in a person's stool, which can indicate gastrointestinal bleeding. The test involves applying a small sample of stool to a guaiac-based reagent, which changes color in the presence of hemoglobin. It is commonly used as a screening tool for conditions such as colorectal cancer or gastrointestinal disorders. A positive result typically requires further investigation to determine the source of the bleeding.
