I was tested for a couple of allergens back in 2016 following an anaphylactic reaction to salmon & the tests also confirmed some of the other things i was allergic to like wheat. i dont react as much to wheat. could there be hope for salmon too?

Most likely, no!: To make a diagnosis of a food allergy you need a history of a reaction like what you describe and the test confirms the diagnosis. Allergy testing positive without a previous reaction has a high false positivity so that is why you tolerate wheat; you do not have clinical allergy. Fish allergies tends to stay specially if you get as adult. I would suggest to avoid, epipen and med alert bracelet
