Food Sensitivity Tests
A recent article was published by CBC Marketplace about the misuse and misinterpretations of IgG tests for food intolerance. The article notes that medical experts, including the Canadian Society of Allergy and Clinical Immunology (CSACI), call IgG tests for food sensitivities “unvalidated,” and more than two dozen organizations warn about the misuse of such tests. Related information will be updated in the Food Allergies Knowledge Pathway soon.
