Food and inhalant allergy test

Inhalant testing can investigate substances breathed in, such as pollen, dust mites, mould or pet dander. Food testing investigates foods associated with a reproducible reaction. Skin-prick testing gives a local response that is assessed by the clinic; blood testing measures specific immune markers. Neither method can diagnose every cause of congestion, cough, stomach upset or rash.

A positive test indicates sensitisation, not automatically a clinically important allergy. A negative test may be reassuring for an immediate reaction but does not replace an assessment of the whole pattern. The timing of symptoms, amount of exposure and findings on examination guide the diagnosis.

Keep a simple record of meals, rooms, seasons, animal contact, symptoms and their onset. Share all medicines and previous severe reactions with the clinician because some drugs can affect skin responses. Never test a suspected severe trigger at home. Follow the agreed plan for avoidance, symptom relief or a supervised food challenge, and ask how to read ingredient labels and manage accidental exposure.

Call emergency services for breathing difficulty, throat swelling, faintness, marked weakness, or symptoms involving several body systems after exposure. This pattern can indicate anaphylaxis. Ongoing wheeze deserves asthma assessment; persistent nose symptoms may occur with allergic rhinitis, and itchy or watery eyes may occur with allergic conjunctivitis.

What exposure does this test address? Which result would change my treatment? Could my current medicines affect accuracy? What should I do if symptoms occur before the appointment?
