PFT stands for Pulmonary Function Test and assesses the lung function by measuring several parameters such as lung volume, capacity, flow rate, and gas exchange. It is the most appropriate test to evaluate the ability of the lungs to take in and expel air and assess the efficiency of gas exchange across the alveolocapillary membrane. The other options, T&A (tonsillectomy and adenoidectomy), ABG (arterial blood gas), AFB (acid-fast bacilli), and URI (upper respiratory infection) do not evaluate lung function in the same way as PFT.
