Question

Quizplus · Accepted Answer

The urea breath test is the most accurate test for H. pylori eradication therapy. This test measures the amount of carbon dioxide a patient exhales after drinking a solution containing urea. If H. pylori is present, it will break down the urea and produce carbon dioxide, which can then be detected. Gastroscopy and gastrointestinal biopsy may be performed to diagnose H. pylori, but they are not typically used to determine the effectiveness of eradication therapy. Barium swallow is a radiologic imaging test that is not specific for H. pylori and is not typically used to evaluate eradication therapy.
