Accurate diagnosis of Helicobacter pylori. 13C-urea breath test

Gastroenterol Clin North Am. 2000 Dec;29(4):885-93, x. doi: 10.1016/s0889-8553(05)70156-4.


The preferred schema for management of Helicobacter pylori infection is diagnosis, treatment, and confirmation of cure. The 13C-urea breath test is ideal for active H. pylori infection for those in whom endoscopy is not required (e.g., those in whom cancer is not suspected) because it offers the combination of simplicity, accuracy, reliability, and absence of exposure to radioactivity. New versions of the test also offer increasing simplicity and lower costs.
