What is a Urea Breath Test?
A urea breath test
helps look at your breath for Helicobacter pylori (H.pylori), a common infection. The H.pylori breath test is a simple method to identify H.pylori bacteria and infection. H.pylori is a general bacteria that cause damage to your stomach or duodenum (the first part of the small intestines). H.pylori bacteria often develop in childhood and can remain in the stomach for a long time if not get treatment. A big reason for H.pylori infection is due to peptic ulcer disease. A peptic ulcer in the stomach is known as a gastric ulcer. It is a form of sores that develops on the lining of your stomach and small intestine. This lining of the stomach helps to prevent the stomach from the strong stomach acid, which digests food. The signs and symptoms of H.pylori infection do not appear as it mostly lives in your stomach lining. In some people, the H.pylori infection leads to stomach cancer and gastritis (inflamed lining of your stomach).
What is the purpose of the H.pylori breath test?
An H.pylori breath test
determines the presence of H.pylori bacteria in your stomach. An H.pylori bacteria lives in your stomach and produces an enzyme called urease that forms urea. Urease helps to convert urea into ammonia and carbon dioxide. A urea breath test measures the traces of carbon dioxide in your breath to find the presence of H.pylori bacteria in your stomach. This test may also suggest for adults and children aged above six years if they can coordinate with the test. An H.pylori breath test
helps your doctor to:
When to conduct this test?
- Diagnose the ulcer in your stomach or upper small intestine.
- Observe an ulcer if you have experienced it in the past and didn’t take this test before.
- Monitors the effectiveness of the treatment if a person has experienced H.pylori infection.
Your healthcare provider may recommend the H.pylori breath test
if you are giving treatment for an H.pylori infection. In general, about 50 % of people had infected with H.pylori bacteria throughout the world. Symptoms of the bacteria do not show up in most people. An H.pylori infection leads to problems in the stomach. Therefore, if you experience any pain in your digestive system, you may need to take this test. You may also place an online

How do I get ready for this test?

- For a second sample, you will need to chew up a tablet or capsule containing urea.
- After 15 to 20 minutes, you will again need to exhale that tablet into a bag similar to a balloon. The amount of carbon dioxide will measure with an instrument or device for a second time.
- The carbon dioxide will release when you take a breath in a bag because your body can absorb it. Your breath samples will go to the laboratory for examination.

with a doctor.
The positive test results
indicate higher carbon dioxide levels in your second sample compared to the first sample. It shows that an H.pylori infection lies in your stomach.
The negative test results
show no difference between the first and second samples of your carbon dioxide. It indicates that there is no H.pylori infection in your stomach.
