The urea breath test (UBT) is a test for diagnosing the presence of a bacterium, Helicobacter pylori (H. pylori) infection in the stomach.
While these bacteria live in your stomach lining, H. pylori make urea, a natural compound in the body.
As the bacteria make urea, they create ammonia and bicarbonate. Traces of these can be found in your breath.
The presence of Urea indicates that you are infected with H. pylori.
H. pylori causes inflammation, ulcers, and atrophy of the stomach.
H. pylori bacteria are spread through contact with feces from an infected person.
If the urea breath test is positive and the isotope is detected in the breath, it means that H. pylori is present in the stomach.
If the isotope is not found in the breath, the test results are negative for the infection.
When the H. pylori is effectively treated (eradicated) with treatment, the test changes from positive (isotope present) to negative (isotope absent).
What other tests might I have along with this test?
Your doctor might also order these tests:
Endoscopy, in which a narrow, lighted tube is put into your stomach through your mouth to look at the lining of your stomach and take out small samples for testing
