Detecting active Helicobacter pylori infection in someone with dyspepsia who has not been treated before is best done with a noninvasive test that directly reflects live bacteria. The urea breath test does exactly that: the patient swallows labeled urea, and if H. pylori is present, the bacteria’s urease enzyme splits it to release labeled CO2 that is measured in the breath. This test has high accuracy (sensitivity and specificity both high), is easy to perform, and clearly indicates whether an active infection is present. It’s preferred over serology, which only shows exposure and can’t distinguish past from current infection, and over invasive endoscopy with biopsy, which is unnecessary when a noninvasive test suffices. A stool antigen test is also a valid noninvasive option and can be used if the breath test isn’t available, but the breath test is typically the first choice due to its robust performance. Remember that recent antibiotics or proton pump inhibitors can affect test accuracy, so they should be paused before testing as advised.
