Which testing may be indicated as part of asthma evaluation under allergy testing, FeNO, labs, and imaging?

• A. Allergy Testing
• B. Cardiac MRI
• C. Stool culture
• D. CT Abdomen

Answer: (A)

Identifying triggers and underlying inflammation is a key part of evaluating asthma. Allergy testing directly fits this goal because it reveals which environmental allergens a patient is sensitized to (such as pollen, dust mites, animal dander, or mold). Knowing these sensitizations helps tailor management: it supports environmental control measures to reduce exposure and can influence treatment decisions, including consideration of therapies targeted at IgE-mediated pathways if indicated.

Cardiac MRI is focused on heart structure and function and isn’t part of routine asthma workup. Stool culture and CT abdomen are unrelated to asthma evaluation and would be guided by gastrointestinal symptoms rather than respiratory concerns.
