When is allergy testing recommended for allergic rhinitis?

A blocked or runny nose, sneezing, and nasal itching can have allergic or non-allergic causes. The clinician considers timing, season, home and work exposures, medicines, and associated eye symptoms before choosing a test. Skin-prick testing and blood testing can look for sensitisation to selected allergens. A positive result must be interpreted alongside symptoms; it does not automatically identify the cause of every flare.

Record when symptoms start, where they occur, possible contact with pollen, dust, mould, animals, or fragrances, and which measures helped. Bring your medicine list and ask whether any antihistamine needs to be paused before testing. Avoid testing panels chosen without a clinical question, since results can create confusion when they do not fit your symptoms. Treatment and practical exposure reduction can begin while the plan is clarified.

Arrange prompt medical review for one-sided persistent blockage, repeated nosebleeds, severe facial swelling, high fever with worsening facial pain, or eye swelling with vision change. Breathing difficulty or swelling of the mouth or throat is an emergency and requires immediate help.

Ask whether your pattern suggests allergic rhinitis, which allergens should be tested, how results would change your plan, and whether another nasal condition should be considered.
