The bacterium Helycobacter pylori is responsible for a large proportion of inflammation and ulcers in the digestive tract and increases the risk of developing tumours in the digestive tract. It colonises the superficial mucus layers of the gastric mucosa, is highly resistant and thrives in the gastric acidic environment. The presence of the bacterium can be detected by a rapid and painless exhalation test.
The patient is given oral C-carbamide in tablet form, and after waiting 10-30 minutes, the exhaled air is blown into a so-called breathing card for 1-4 minutes. When the test is finished, the card is placed in a measuring device, which immediately shows the result.
The tablets taken during the test contain the carbon isotope C14, a naturally occurring radioactive isotope found in the air and in the human body. The patient will only be exposed to a level of radiation equivalent to the radiation received from naturally occurring background environmental radiation over a 24-hour period.
Nevertheless, the test is not recommended:
