Stool PCR

Stool PCR (polymerase chain reaction) is a molecular diagnostic technique used to detect the presence of specific pathogens, such as bacteria, viruses, or parasites, in stool samples by amplifying their genetic material. This method is crucial in clinical practice for rapid and accurate identification of infectious agents, particularly in cases of gastroenteritis, where timely diagnosis can guide appropriate treatment. A key association is its use in diagnosing infections like Clostridium difficile, which can lead to severe colitis.
