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. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide.
Carbon urea breath tests have a high sensitivity and specificity for the diagnosis of H. pylori. [ 136 ] Proton-pump inhibitors and antibiotics should be discontinued for at least 30 days prior to testing for H. pylori infection or eradication, as both agents inhibit H. pylori growth and may lead to false negative results.

Rapid urease test, also known as the CLO test (Campylobacter-like organism test), is a rapid diagnostic test for diagnosis of Helicobacter pylori. [1] The basis of the test is the ability of H. pylori to secrete the urease enzyme, which catalyzes the conversion of urea to ammonia and carbon dioxide .
Common side effects include abdominal pain, nausea, headaches, and muscle pains. [6] Serious side effects may include rhabdomyolysis, liver problems, and diabetes. [6] Use during pregnancy may harm the baby. [6] Like all statins, rosuvastatin works by inhibiting HMG-CoA reductase, an enzyme found in the liver that plays a role in producing ...
Patients should be queried about any side effects, missed doses, and completion of therapy. As culture with antibiotic sensitivities is not routinely performed when a H. pylori infection is diagnosed, it is generally recommended that different antibiotics be given at higher doses for 14 days. [2]
Gastritis caused by H. pylori infection is termed Helicobacter pylori induced gastritis, and listed as a disease in ICD11. [ 6 ] [ 7 ] More than 80% of individuals infected with the bacterium are asymptomatic and it has been postulated that it may play an important role in the natural stomach ecology.
H. pylori can be diagnosed by testing the blood for antibodies, a urea breath test, testing the stool for signs of the bacteria, or a biopsy of the stomach. [1] Other conditions that produce similar symptoms include stomach cancer, coronary heart disease, and inflammation of the stomach lining or gallbladder inflammation. [1]
The presence of Helicobacter pylori (in peptic ulcer disease) can be tested for with the urea breath test. Exhaled nitric oxide is a breath test that might signal airway inflammation such as in asthma. Breath tests for diseases have been developed for early detection of lung cancer, breast cancer, pulmonary tuberculosis and many others, to ...
