Description
Mei Wu and four co-authors find in 2026 the best wait time between a stomach scope exam and a breath test for a common stomach germ. The germ, Helicobacter pylori, drives stomach cancer risk, so exact detection guides cure efforts. Breath tests done the same day as a scope exam may read falsely.
Records cover 298 adults tested at one, two, or four hours after the scope exam. Tissue checks serve as the reference standard, with infection in 47 percent of cases. Agreement runs strong at all three waits. The two-hour wait posts the top specificity at 96.2 percent. False negatives are probed against tissue traits. The authors back two hours as the sweet spot for same-day testing.
