Food Intolerance Testing is a vague reference. It does not involve the immune system. We use the term intermittently because it is what people search for when trying to access our services.

The term Food Sensitivity Testing better describes the laboratory blood test service that we provide:

  • Where specific foods activate the immune system

  • Resulting in IgG antibody production

  • Where inflammation is the result.

Consequently, we use a CE (European Conformity) marked test to measure the level of IgG antibodies triggered by individual foods. Scientific publications clearly highlight how a significantly elevated antibody response to food is not normal.

Could your condition be caused by food sensitivity?

See this 3 minute video (below) to find out more.

Our food sensitivity test is used in over 200  Laboratories Internationally to provide the optimal testing service for people across the globe.
