Experimental: Helicobacter Pylori Screening and Treatment

Participants in this single-arm study will undergo screening for Helicobacter pylori (H. pylori) using the PYtest® 14C-Urea Capsule Breath Test. This FDA-approved, non-invasive diagnostic method involves swallowing a radiolabeled urea capsule. If gastric urease from H. pylori is present, the urea is hydrolyzed to produce carbon dioxide and ammonia. Ten minutes after ingestion, a breath sample is collected in a balloon and transferred into a collection fluid to trap the labeled carbon dioxide. The sample is analyzed using a liquid scintillation counter to determine infection status.~Participants who test positive will receive VOQUEZNA® Triple Pak® therapy, dispensed by the study team at the time of diagnosis. Phathom Pharmaceuticals will supply the medications (which include complete medication package insert), but the study team hold and dispenses medications.
