In a child with asthma, allergy testing is not diagnostic but may be considered. Which statement best reflects this?

• A. It is diagnostic of asthma.
• B. It is not diagnostic of asthma but may be considered.
• C. It should be done routinely for all asthma patients.
• D. It is contraindicated in asthma.

Answer: (B)

Allergy testing detects sensitization to specific allergens, but it does not prove that a child has asthma. The diagnosis of asthma comes from a history of symptoms (like recurrent wheeze, coughing, chest tightness) and objective evidence of reversible airway obstruction or airway hyperresponsiveness. Allergy testing can be useful because it helps identify triggers and guide management—such as environmental control measures, treatment of coexisting allergic rhinitis, and consideration of allergen immunotherapy or certain biologic therapies in selected cases. It’s not something done routinely for all asthma patients, and a positive result does not by itself diagnose asthma.
