Allergy diagnosis starts with a detailed history—seasonal vs perennial symptoms, relation to food, insect stings, or medications. We examine for comorbidities (asthma, eczema) and may trial intranasal steroids or antihistamines before referral. For patient education, Health Canada’s allergies overview summarizes common triggers. Skin prick testing, specific IgE, and supervised oral food challenges are typically performed by allergists; unproven “food sensitivity” blood panels are discouraged.

Frequently Asked Questions
Most skin prick testing and challenges are done by allergists; primary care focuses on history and triage.
We teach autoinjector use, when to call 911, and replace-before-expiry reminders.
Oral challenges happen in supervised settings with resuscitation equipment—not at home.
Specific IgE can help in context but must be interpreted with history—broad panels often cause false positives.
