I had a pulmonary function test and my doctor called me back and said that my lung capacity was normal but my lung function improved a little bit after given the bronchodilator. He said that wasnt enough to give me the diagnosis of asthma. why is this?
The PFT report indicate bout you lung function parameters likeFEV1,FCC, PEFR. There are certain definitive parameters to determine whether you have obstructive airway disorder like change of more than 20% in PEER, >200ml in FCC etc. depending on which you are diagnosed as atheist.
