In outpatient clinics, patients often come to consult with medical reports and find that H.pylori is positive. I don’t know what to do?

First of all, the current physical examination is paying more and more attention to the detection of H.pylori, which shows that H.pylori is getting more and more attention, especially in areas with a high incidence of gastric cancer. Once H.pylori is found, clinical eradication is currently advocated.

Secondly, there are two main methods for detecting H.pylori in physical examination, one is carbon 13 breath test, and the other is serum H.pylori antibody detection. 

The carbon 13 breath test is a non-invasive detection method. The result of detecting H.pylori is more accurate. If it is positive, it indicates H.pylori infection; 

the serum H.pylori antibody test is an invasive detection method that detects H.pylori in the serum Antibody, a positive value indicates that the tested person has been infected with H.pylori. Since the antibody produced after being infected with H.pylori will remain in the serum for a certain period of time, it may exist that the tested person has eradicated H.pylori, but there is still in the serum If the H.pylori antibody is tested positive, this is a false positive result. 

Therefore, a positive serum antibody test does not indicate that the subject is currently infected. Only if the tested person has not taken H.pylori eradication drugs in the past three months and tested positive for seroantibodies, it may indicate H.pylori infection. Therefore, patients who have a positive serum antibody test are recommended to perform another carbon-13 breath test.
