How are allergies diagnosed?
Through your history plus skin-prick or specific-IgE blood tests to identify triggers. A specialist interprets these together with your symptoms.

Anaphylaxis (swelling, breathing trouble, collapse) is an emergency — use an adrenaline auto-injector if prescribed and call emergency services immediately.
