Shellfish Allergy in Children: Symptoms, Diagnosis, Testing & Treatment

Shellfish allergy can feel scary—especially when reactions can be sudden and severe. In this episode, we break down shellfish allergy in a clear, practical way: common symptoms (from hives to breathing problems), when to suspect anaphylaxis, and what to do in the moment. We also cover diagnosis and testing (skin prick tests, blood IgE, and when an oral food challenge might be considered), plus the tricky stuff like cross-contact in restaurants, takeaway risks, and food labels.Whether you’re a parent, teenager, or clinician, you’ll leave with a confident plan—how to avoid shellfish safely, when to carry and use an adrenaline auto-injector, and how to manage school, travel, and eating out without living in fear.Sources:Gerez, I.F.A., Llanora, G., Yap, G.C., Cheng, Y.K., Thong, B.Y., Tang, C.Y., Van Bever, H.P.S., Shek, L.P.C., Curotto de Lafaille, M.A. and Lee, B.W.
