follow up for Helicobacter pylori eradication therapy

Urea breath test, stool antigen test, or biopsy 4–6 weeks after completion of therapy.

Serology is not preferred to confirm eradication, as it remains positive for weeks/months after eradication.

(Stop PPIs at least 2 weeks before urea breath test for accurate results.)
