Summary

This study screens people in South Florida for H. pylori, a stomach infection that can lead to chronic gastritis, ulcers, and even stomach cancer. Those who test positive receive treatment, and the study compares at-home breath testing versus in-person retesting to confirm the infection is gone. The goal is to make screening easier and prevent serious stomach diseases.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: PYTEST® 14C-Urea Capsule Breath Test (at-home and in-person)
What this could lead to: If successful, this could show that at-home testing is as effective as in-person retesting for confirming H. pylori eradication, making screening more accessible and helping prevent stomach cancer.
What could go wrong: This is a small, single-site study (75 participants) focused on testing methods, not a large-scale prevention trial. The at-home test may be less accurate or harder to complete than in-person testing.
