Which of the following is NOT an indication for pulmonary function testing (PFT)?

Pulmonary function testing is used when you need to quantify how well the lungs are working to diagnose disease, guide management, or assess risk before procedures. It measures airflow, lung volumes, and gas exchange, providing objective data that you can’t get from a routine blood test. Routine annual complete blood count is not an indication for PFT because CBC evaluates blood components and hematologic status, not lung mechanics or gas transfer. Screening for smokers with PFTs isn’t routinely recommended in asymptomatic individuals, since screening all smokers with lung function testing hasn’t shown clear benefit and could lead to unnecessary follow-up. PFTs are more appropriate when there are symptoms or risk factors suggesting lung disease. Diagnosing shortness of breath, exertional dyspnea, or cough is a classic indication for PFT, as it helps distinguish obstructive from restrictive patterns and identifies underlying causes, guiding treatment. PFTs are also indicated for prognosis in preoperative or disability assessments, where measuring respiratory reserve helps estimate perioperative risk and overall fitness for surgery or work capacity.
