I have reason to believe that we can add macadamia nuts to Henry’s list of allergies. And that it’s at least as bad as any of the others. I’ll try to have them add it to the battery of tests when he goes for his yearly retest in February.
To review, the official ones that are “oral allergy syndrome” are:
Dairy
Eggs
Peanuts
The one that tests fine for OAS but provokes a strong reaction in keeping with a crossover with latex allergy (of which he’s shown little sign) is:
Banana
He seems to have outgrown, or mostly so, a sensitivity to salicylates and azo dyes, degree of which depended on which color, and to some component of screen printing ink on contact with it.
