Information

How to prepare

The 13C breath test is a safe and non-invasive test used to detect the presence of Helicobacter pylori (H. pylori) bacteria in the stomach. This bacterium is common in humans and may be associated with inflammation of the stomach lining, the formation of ulcers, and even the development of stomach cancer.

During the test, the patient drinks a solution containing a small amount of 13C-labelled urea. If H. pylori is present in the stomach, the bacteria break down this substance and release carbon dioxide (CO₂), which enters the bloodstream and is then exhaled. Breath samples are analysed to detect the presence of labelled CO₂. If it is detected, the test yields a positive result for H. pylori infection.

The test is quick and convenient, usually taking about 30 minutes, and the patient does not experience any discomfort during the procedure.

How to prepare for the test

Four weeks before the test:

  • Do not take antibiotics.

Two weeks before the test:

  • Do not take probiotics, magnesium, or omeprazole.
  • Do not take laxatives, stool softeners, or stool bulking agents. You should also avoid any tests that require bowel preparation, such as a colonoscopy or barium enema.

Two to three days before the test:

  • It is recommended to consume only the following foods and beverages: white bread, white rice, white potatoes, baked or grilled chicken or fish, water, and black coffee or tea without flavouring.
  • Do not eat or drink anything else – this may lead to inaccurate test results.
  • In particular, avoid beans, pasta, fibre-rich grains, and foods high in fibre.

The day before the test:

  • Have an early dinner (at least 14 hours before the test) consisting of rice and grilled or baked chicken or fish.
  • You should fast for 12 hours before the breath test begins. This means you must not eat or drink anything other than water.
  • You may continue taking your usual prescription medications with water. Please bring all your prescription medicines with you to the appointment.

On the day of the test:

  • You must not eat or drink anything in the morning.
  • You may take your medications with a small amount of water. If you have diabetes treated with insulin or diabetes tablets, ask your doctor if you should adjust your morning dose.
  • Brush your teeth before the test.
  • Before or during the test, do not eat, drink, chew gum or tobacco, smoke cigarettes, or use breath fresheners or sweets.
