Coeliac disease is an auto-immune condition, which isn’t very common. It affects 1% of the population or so. AIRE measures gut fermentation levels, which is unrelated to Coeliac disease and gluten intolerance.

If you think that you may have an intolerance or sensitivity to gluten, it would be best to get this tested with your physician. Gluten intolerance is an immune response to gluten proteins. Our products test for different biomarkers and wouldn’t be the ideal tool for testing gluten intolerance.

Yes. If you purchase the food intolerance testing kit, you can test your reaction to four common FODMAPs including lactose, fructose, sorbitol and inulin. If you suspect you may have lactose intolerance, you can select this as your first test.

AIRE detects hydrogen, which is produced by your gut bacteria when they come in contact with food that hasn’t been fully digested yet. Any given species of bacteria will only be able to break down certain foods, so the foods that produce large amounts of gas in your gut, will depend on the types of gut bacteria you have. This is one of the main reasons why everyone is completely unique in terms of digestion of food.

To achieve success with our products, we recommend one device per user.

Our devices can be used by children under the guidance of an adult. Use for children is exactly the same as it is for adults.

The quantities of the FODMAP substrates are also safe for children.

AIRE is not suitable for use by babies / toddlers, because of the breathing technique required to perform a breath test.

Most people will tend to take 4-6 weeks to get a good handle on which foods are most suited to their digestion. There are some people who just want to test one or two food components, which is valuable and can be done more quickly. Then, on the other end of the spectrum, some people will track their response to food over several months or will start using the device again after a lifestyle change (e.g. change in diet) as that can often affect how you digest food.

Yes, it’s possible for us to share your results securely with your doctor, as long as we get your consent. Assuming your doctor is comfortable to proceed, just send an email to with contact details for your doctor and we’ll take it from there.

By making breath testing a part of your day, you can discover a lot about your gut. If you manage to take between 8-10 breath tests each day, you are doing an excellent job. Here’s a good approach to daily breath testing:

  • Take a baseline breath test once you wake up, after brushing your teeth and before eating food.
  • Wait until one hour after your breakfast, then test hourly until your lunch.
  • After lunch, wait an hour, then test hourly until your next meal and so on until you reach a maximum of 10 tests.
