Conditions & Services

A full-service allergy clinic

We test for and manage the full range of allergic and immune conditions, tailored to each patient by referral. Hover any card for more.

Allergy skin testing

Skin prick testing for environmental allergens, foods, insect venom, and drugs.

A small drop of each allergen is placed on the skin and gently pricked. Results usually show within about 15 to 20 minutes, in a single visit.

Patch testing

For contact dermatitis from fragrances, metals, and preservatives.

Patches are worn on the back for about 48 hours, then read over follow-up visits to find what your skin is reacting to.

Oral food challenges

Controlled ingestion of a suspected allergen under medical supervision.

Done in clinic with the care team present, to confirm whether a food is truly a problem or can be reintroduced safely.

Chronic hives (urticaria)

Investigating and managing unexplained or recurring hives and swelling.

We look for triggers and patterns, then build a plan to reduce flare-ups and keep you more comfortable.

Anaphylaxis management

Epinephrine auto-injector guidance and personalized action plans.

We help you recognize early signs, carry and use your auto-injector confidently, and plan ahead for emergencies.

Asthma management

Spirometry, inhaler education, and biologic therapy where appropriate.

We assess your breathing, refine inhaler technique, and consider advanced options for harder to control asthma.
