Does allergy testing treat asthma?

Asthma involves sensitive, narrowed airways. Allergens such as dust mites, pets, mould or pollen can aggravate symptoms in some people, but asthma can also be triggered by infections, exercise, smoke, weather or other irritants. A skin-prick or blood test looks for signs of sensitivity; a positive result does not prove that the allergen causes every episode. Your clinician matches the result with your symptoms, exposure pattern and examination.

Treatment focuses on controlling airway inflammation and relieving narrowing. This may include an inhaler plan and trigger reduction. In selected people with allergy-driven symptoms, specialist treatment aimed at changing the immune response may be considered, but that is different from the diagnostic test.

Keep a brief record of wheeze, cough, chest tightness and possible exposures, including where you were and what happened beforehand. Take your prescribed inhalers as directed and do not stop a preventer because testing identifies no allergy. Reduce a confirmed trigger when practical, such as improving bedroom dust control or avoiding smoke. Ask whether your inhaler technique and written asthma action plan need checking.

Seek urgent medical help for severe breathlessness, difficulty speaking, blue or grey lips, marked drowsiness, or symptoms that rapidly worsen. Use your personal asthma action plan if you have one. Arrange prompt clinical review when symptoms are repeatedly waking you, limiting activity, or needing reliever medicine more often than advised; allergy testing should not delay treatment of breathing difficulty.

Could an allergy be contributing to my pattern of symptoms? Which test is appropriate, and how will you interpret it alongside my history? What should I change if a trigger is confirmed? Does my current inhaler plan need adjustment, and when should I seek emergency help?
