Order your intolerance breath tests online

Your results

We now offer online ordering of specific breath tests due to repeated requests for reliable testing. Most, but not all countries allow import of the test sugars (not possible, e.g. for the USA, Canada and Australia). The validated tests1 for food intolerances can now be performed at home or anywhere convenient. The test kit consists of instructions, glass tubes for breath samples, and the desired test sugar. The test kit will arrive by post or courier and the completed test is returned to us using the same packaging.

Please be aware that several other diseases may cause similar symptoms or signs to those provoked by food intolerances and we recommend you consult your doctor about your symptoms for exclusion of diseases other than food intolerances. Breath testing for gastrointestinal symptoms will not exclude inflammatory or cancer or any other diseases. Food intolerance may be caused by underlying diseases, such as celiac’s disease or inflammatory bowel disease, again emphasizing the need for you to consult with your doctor about your symptoms. During the breath testing you will be swallowing sugars that may provoke symptoms. This is obviously part of the test procedure and result. However, this is another reason why we recommend you perform the diagnostic process under the guidance of your doctor.
