Features of the breath test
This method can be used in adults or patients who are able to hold their breath for a short period of time. The patient inhales deeply, holds his breath, then exhales slowly through the mouthpiece. Within 45 seconds the result will be displayed on the screen and can be saved to the patient profile, uploaded to the GastroCHARTTM database or recorded manually. Then the patient should drink the solution and repeat the breath test after half an hour. The test lasts 2 hours. During the whole test it is forbidden to drink water, smoke and eat. There are no functional restrictions during the test (between exhalations). For younger children who cannot perform the technique described above, a mask is available for use.
