The Urea Breath Test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease. Patients swallow urea labeled with an uncommon isotope, either radioactive Carbon-14 or non-radioactive Carbon-13. In the subsequent 10-30 minutes, the detection of isotope-labeled carbon dioxide in the breath indicates that the urea was split; this indicates that urease (the enzyme that H. pylori uses to metabolizeMetabolism in the most general sense, is the ingestion and breakdown of complex compounds, coupled with the liberation of energy, and the consequent generation of waste products. It is major process of living organisms, and because this process can happen urea) is present in the stomachIn anatomy, the stomach is an organ in the alimentary canal used to digest food. Generally, the stomach's primary function is not the adsorption of nutrients from digested food; this task is usually performed by the intestine. Latin names for the stomach, and hence that H. pylori bacteria are present.

UreaUrea is an organic compound of carbon, nitrogen, oxygen and hydrogen, with the formula C O N H and the structure: In animals, the individual atoms of urea come from carbon dioxide, water, aspartate and ammonia in a metabolic pathway known as the urea cycl	Urea cycleThe Urea Cycle is a cycle of biochemical reactions occurring in many animal organisms that produces urea from ammonia. This cycle, also known as ornithine cycle, was the first metabolic cycle discovered (Krebs and Hensenleit, 1932) Urea is much less toxic	Urea Breath TestThe Urea Breath Test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease.

The reaction occurs as follows: (NH)CO + 3HO → CO + 2NHOH In 1926 James Sumner shows that urease is a protein.

A urea cycle disorder is a genetic disorder caused by a deficiency of one of the enzymes in the urea cycle which is responsible for removing ammonia from the blood stream.
