Urea C 14
Urea C-14 is a radioactively labeled form of urea containing carbon-14 used in the 14C-urea breath test for non-invasive detection of Helicobacter pylori infection in the stomach. H. pylori-produced urease hydrolyzes the ingested 14C-urea to produce 14CO2, which is measured in exhaled breath by liquid scintillation counting, indicating active infection. Unlike the 13C version, the 14C test involves low-level radiation exposure, limiting use in pregnant women and children.
