About GI Cognition

GI Cognition is a London company, incorporated in 2016 and led by Dr Jafar Jafari, that provides gut physiology testing. It works in four ways: a clinic in London, mobile testing for hospitals, remote reporting for other clinicians, and Gut Insights home test kits sold online.

The home kits are breath tests. You order online, the kit is posted to you, you collect breath samples at home following the instructions and return them to the company's UK laboratory. Results are reviewed by its specialist team and sent by email, and you can book a follow-up consultation if you want to discuss them.

Kits currently range from £125 for the H. pylori breath test to £299 for the glucose-based tests, with several on limited-period offer prices. The company says it is registered with the Care Quality Commission and with the MHRA as a maker of in vitro diagnostic devices. Speak to your GP or pharmacist if you have any concerns about your health.

  • Ask whether your private health insurance covers clinic tests before booking.
