Urea C 13
Urea C-13 is a stable isotope-labeled form of urea containing carbon-13, used primarily as a diagnostic agent in the 13C-urea breath test to detect active Helicobacter pylori infection in the gastrointestinal tract. After oral ingestion, H. pylori urease cleaves 13C-urea to produce 13CO2, which is detected in exhaled breath, providing a non-invasive, radiation-free diagnostic test. It is also used in metabolic research studies investigating urea cycle function and protein metabolism.
