Helicobacter pylori (H. pylori) Antigen, Stool
Detects active H.About Test
H. pylori Antigen Stool Test detects the presence of Helicobacter pylori bacteria in the digestive system through a stool sample.
H. pylori is a common bacteria that infects the stomach lining and can cause gastritis, stomach ulcers, and long-term digestive issues. If untreated, it may increase the risk of stomach cancer.

It is also commonly used to confirm whether the infection has been successfully treated.
