We had a crazy allergist who was adamant that DS1 was skinny because he was eating foods he was allergic to so she went on a fishing expedition via blood and spt...
He tests positive to wheat, rye, barley, rice, corn, oats, soy, dairy, peanuts and the majority of tree nuts via both tests.
He only has reactions to wheat, rye, barley and egg. (FWIW, I reintroduced the majority of his "allergens" that he had been eating prior with no issue - we did challenge peanuts and tree nuts with the new allergist. He had prior issues with straight milk but tolerated milk based products).
This allergist was coo coo for cocoa puffs. But she is also the reason that I research, research, RESEARCH allergists prior to make sure they have a clue about food allergies and are not environmental allergists parading as food allergy specialists.
