As a general rule of thumb, we recommend taking a breath test before eating and again approximately one hour after you eat. The AIRE app allows you to set a breath test reminder for an hour after you log your food. 

If you would like to add more breath tests, we recommend doing them at hourly intervals (for example one hour, two hours and three hours after eating). 

We recommend not exceeding 12 breath tests on a regular day and 20 breath tests on a day when you do a Food Challenge.

In general, any breath tests are better than none, so don’t worry if you don’t get your timing exactly right. You might still see interesting results up to four hours after eating!
