Pulmonary Function Test

A pulmonary function test determines how your lungs function by measuring the amount of air your lungs hold and how fast the air enters and exits your respiratory system. Common asthma tests include spirometry and methacholine challenge. However, a broad scope of pulmonary function tests can be used to diagnose many lung conditions besides asthma.
