If a patient has a documented aspirin sensitivity, what should be performed to confirm diagnosis?

When a patient has a documented aspirin sensitivity, the most definitive way to confirm the diagnosis is through an aspirin challenge test. This test involves administering aspirin in a controlled setting, where the patient's response can be closely monitored for any adverse effects, including respiratory reactions typical of asthma exacerbation.

The aspirin challenge test is considered the gold standard for confirming aspirin sensitivity because it directly assesses the patient's reaction to the drug. This helps to clarify whether the patient's symptoms are indeed related to aspirin use and can inform future management and treatment plans for their asthma or associated conditions.

In contrast, other testing options, such as an allergy panel, are generally geared towards identifying more common allergens but do not specifically assess the sensitivity to aspirin. The FEV1 test, which measures how much air a person can forcefully exhale in one second, evaluates lung function but does not provide direct information regarding aspirin sensitivity. Similarly, CPR training is entirely unrelated to confirming a diagnosis of aspirin sensitivity and would not provide useful information in this context.
