Urease expiration test

What is the Urea Breath Test?

The urea breath test is a painless, non-invasive diagnostic test used to detect the presence of Helicobacter pylori (H. pylori) bacteria in the stomach. This bacterium can contribute to stomach ulcers and other digestive issues. The tablet taken during the examination contains carbon-14 (C-14) isotope, which is a naturally occurring radioactive isotope found in the air and the human body. The patient is exposed to a radiation dose equivalent to the amount received from natural background radiation over 24 hours.

When is the test needed?

Your doctor may recommend the test if you experience:  
-    stomach pain or burning sensation
-    frequent heartburn or acid reflux
-    bloating or nausea
-    recurrent digestive problems
-    suspected H. pylori infection or follow-up after treatment

How is the test performed?

The test is performed on an empty stomach and takes approximately 30 minutes.
1. Baseline Breath Sample – You will blow into a special device to measure your initial breath sample.
2. Urea Solution Intake – You will drink a small amount of a safe urea-containing solution. If H. pylori is present in your stomach, the bacteria will break down the urea, releasing carbon dioxide.
3. Second Breath Sample – After a short period, you will blow into the device again to measure the carbon dioxide levels in your breath.
