Experimental: At-Home Retesting Strategy

Participants who test positive for H. pylori (HP), will receive a kit that contains a PYtest® 14C-Urea Breath Test (TriMed). Participants will complete the retest at-home at least 6 weeks after treatment. Study team will contact the participant to inquire about retesting and the post treatment survey. The kit will include an envelope, materials for the test, and a return form. PYtest® is a quantitative and non-invasive method for the diagnosis of HP. The test is conducted with the swallowing of a urea capsule. If gastric urease from HP is present, the urea is split to form carbon dioxide and ammonia. Ten minutes after the capsule is ingested, a breath sample is collected in a balloon. The balloon is tied and mailed along with the return form to be analyzed by an outside laboratory. The study team will call the participant to provide results. Those who retest positive will be instructed to seek treatment from their primary care provider.

Active_comparator: Standard Care Retesting Strategy

Participants who test positive for H. pylori (HP), will complete their retest in-person with the study team. Study team will contact the participant to inquire about scheduling the retest and the post treatment survey. Retest will be completed in Don Soffer or at one of study's community sites. PYtest® is a urea breath test and is a quantitative and non-invasive method for the diagnosis of HP. The test is conducted with the participant swallowing a urea capsule. If gastric urease from HP is present, the urea is split to form carbon dioxide and ammonia. Ten minutes after the capsule is ingested by the participant, a breath sample is collected in a balloon. This liquid is analyzed on site by the liquid scintillation counter, by the study team. Those who test positive will be instructed to seek treatment for H. pylori infection.
