What is the purpose of an allergy test?

The purpose of an allergy test is primarily to identify allergens that are responsible for triggering allergic reactions in individuals. This testing helps healthcare providers determine which specific substances—such as certain foods, pollen, pet dander, or medications—are causing an adverse immune response in the patient. By pinpointing these allergens, appropriate management strategies can be established to minimize exposure and manage symptoms effectively, improving the patient's quality of life.

Further context around the other areas helps clarify why they are not aligned with the primary aim of an allergy test: evaluating immune function typically involves broader immunological assessments, assessing cardiac function looks at the health of the heart and circulatory system, and diagnosing leukemia involves hematological investigations to determine blood cell abnormalities. Each of these serves distinct purposes in medical diagnostics separate from identifying allergens.
