I'm looking for some insight about a possible Catfish allergy.
My almost 3 yr old daughter was recently diagnosed with allergies to peanut and sesame. She has never had a full-blown reaction, but had oral symptoms to both. Subsequently she seems to have reacted to eating Catfish even though she has eaten various fish in her life without problem. Initially it presented as very bad, sudden hayfever symptoms (rhinitis, itchy nose and eyes). Then her eczema flared up and her face got very red. Eventually one eye swelled (she was rubbing it alot). She never developed any oral, gastro, or respiratory symptoms and even continued to eat it. Our allergist is 3 hrs away so our family doctor ordered a blood test for seafood mix. It came back negative. Tonight she had a similar, although milder, reaction to Cod.
What's up? Is it possible she is only allergic to Catfish and the blood test didn't detect it because it isn't included in the test mix? Is there a skin test serum specific to Catfish? Is she just at the early stages of sensitization? Should we be rereferred to the allergist for fish allergy skin testing?
