Polymerase chain reaction

The polymerase chain reaction technology requires only a small amount of DNA to detect the presence of H. pylori, and does not require the presence of live bacteria (this is different from other H. pylori detection methods). It can not only detect H. pylori in the stomach, but also detect it. Sites other than the stomach, such as plaque and H. pylori in feces, can also be used for epidemiological investigations. Its sensitivity is far superior to other methods, which is helpful for determining the source and pathway of bacterial infection. A promising method for H. pylori detection.
