A review of H pylori testing suggested that :
-
both the 13C-urea breath and stool antigen tests are accurate methods for testing for H. pylori after eradication therapy
-
serological tests are of no value in confirming successful eradication, as the antibody persists long after successful eradication
-
C-urea breath tests and stool antigen tests are generally more accurate than serological tests and they can be used both pre- and post-treatment
