RE: List of bodies that recommend not using IGG tests22 Nov 2023 10:32
From Canadian allergy society
Additionally, and perhaps of greater potential concern, a person with a true immunoglobulin E (IgE)-mediated food allergy, who is at significant risk for life-threatening anaphylaxis, may very well not have elevated levels of specific IgG to their particular allergen, and may be inappropriately advised to reintroduce this potentially deadly item into their diet.
This has law suit written all over it...in a country that is litigation happy..eg target market of USA
Maybe best they don't sell much there?
