He also said there is no current evidence supporting IgG testing, Vega testing, or muscle strength testing in the investigation of suspected IgE-mediated food allergy. “What I tell patients is that if any of these tests identifies something, it probably identifies something that’s mild and very temporary, because in my experience patients with positive IgG tests are usually told to avoid the food for 1-4 months and then to reintroduce that food in a rotation basis. Avoidance of food allergens based on this type of testing is not necessary. However, for patients who still wish to practice short term avoidance of the food then this is fine provided the diet does not compromise nutrition.”
Dr. Bergman reported having no financial disclosures.
