What is Helicobacter pylori?
Helicobacter pylori (or H pylori) is a type of bacteria that is responsible for many cases of chronic gastritis and stomach ulcers.
Urea breath tests are a sensitive and specific test and is an ideal test for determining the success of eradication therapy. It is also useful in those situations where endoscopy is not indicated.
What is a urea breath test?
Urea breath test (or UBT test) is a simple, sensitive and non-invasive way of testing patients to determine H. pylori status.
How is a urea breath test performed?
Certain medications that may affect the test need to be excluded, for up to 30 days before the test. A small dose containing Carbon-13 Urea (13C urea) is taken by mouth, and a breath sample is collected 30 minutes later. The test is not radioactive and can be performed on children, or pregnant women.

Why would you need a urea breath test?
Nobel-Prize-winning research in Western Australia has recently (within the last 10-15 years) identified Helicobacter pylori as a major treatable cause of ulcers of the stomach and duodenum, and to a lesser extent gastritis (inflammation of the stomach lining). Symptoms of these conditions include:
Upper abdominal pain
Upper abdominal pain, particularly pain where the timing is related to food or lack of food, and nausea or vomiting.
Heartburn or acid reflux is a similar symptom that is less consistently related to gastritis and H pylori as a cause.
Urea breath test results explained
A POSTIVE urea breath test for Helicobacter pylori means that the bacterium is present within the stomach, and may therefore be the cause of upper abdominal symptoms. H pylori eradication therapy may be prescribed by your doctor to kill the bacterium and therefore allow healing to occur.
A NEGATIVE urea breath test for Helicobacter pylori means that the bacterium probably is not present within the stomach, although it is possible for so-called false negatives to occur when certain medications are not witheld before the test.
