A member asked:
If you fail a pft does it mean you have asthma?
4 doctors weighed in across 2 answers
PFT: Failing a pft could be due to different reasons, not necesarily due to asthma, your clinical history is more important than the pft to say if you have asthma, then the pfts, and sometimes we are not sure and have to wait or do other tests.

Not necessarily: "failing" a pft can mean the presence of obstruction like in asthma or COPD but there can also be restrictive lung disease which is caused by a whole lot of diseases including fibrosis, musculoskeletal disease, etc. There is also a diffusing capacity which could be abnormal due to many factors. So, not all abnormal pfts mean asthma is present!
