What does carbon 14 mean?

Carbon-14 is the carbon-14 breath test indicator. The carbon-14 breath test indicator is a method used to diagnose the presence of H. pylori infection.

The carbon-14 breath test indicator is a noninvasive test used to detect the presence of H. pylori infection. After the subject takes urea containing carbon-14 labels, if H. pylori is present in the stomach, the urease produced by it breaks down the urea into ammonia and carbon-14 labeled carbon dioxide, which passes through the blood into the lungs and is exhaled. Therefore, by collecting the breath of the subject and measuring the amount of carbon-14 labeled carbon dioxide therein, it is possible to determine whether H. pylori infection is present.
