Also Known As:
A Pulmonary Function Test (PFT) with bronchodilator is a diagnostic assessment used to evaluate how well the lungs work and to determine whether airway obstruction is reversible. The test begins with baseline spirometry, Where the patient performs FVL, SVC and MVV. After baseline measurements, the patient inhales a bronchodilator medication—commonly asthalin—and the spirometry is repeated after 10–15 minutes. The purpose is to evaluate bronchodilator responsiveness. A significant improvement, typically defined as an increase in FEV₁ or FVC by ≥12% and ≥200 mL, suggests reversible airway obstruction, as seen in asthma. Limited or no improvement may indicate conditions such as COPD, where reversibility is less pronounced.
Overall, a PFT with bronchodilator helps clinicians differentiate respiratory diseases, assess severity, and guide management decisions.
1) If patient is asthmatic, to bring their puff with them to tackle any emergency.
2) If there is history of cough with heamoptysis / active pulmonary tuberculosis (sputum positive) then PFT is contraindicated.
3) Patient should be able to follow instructions given by techies.
4) Recent admission because of heart disease.

TAT Policy
The Turnaround Time (TAT) for a test depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
Please note that in uncommon circumstances, TAT may be delayed due to the complexity of the test or reasons beyond our control. You will be informed about the estimated TAT at the time of registration or after completion of the test.
