35 Years Experience


Do you suffer from bloating, irritable bowel, or reflux?

Fitzwilliam Food Test Clinic is an Irish company and has more than 35 years of clinical experience in treating such conditions. Diet and especially undigested food (food intolerance) are often at the root of such problems.

About Our Food Intolerance Test

We use laboratory blood tests to assist people to make positive changes in their dietary choices. These tests are high sensitivity, antibody tests. They have been designed to guide you through your food elimination process.

The tests are CE mark certified in full compliance with EU regulation of medical tests. They are medical-grade tests so you can have confidence in your food intolerance testing results.
