A gastrointestinal pathogen Polymerase Chain Reaction (PCR) test is a diagnostic tool used to detect the presence of various microorganisms that cause disease in the gastrointestinal tract. The test is important because it provides rapid, accurate, and comprehensive detection of pathogens causing gastrointestinal infections. It supports timely diagnosis, appropriate treatment, outbreak control, and public health surveillance efforts, ultimately improving patient outcomes and reducing the burden of gastrointestinal diseases.
