Hi SaedSak - excellent question.
You may be aware we cannot provide medical advice or diagnostics over the internet (for your own safety). Based on your inquiry, I thought this article might provide you with some additional insight for your expressed concern: https://copd.net/diagnosis/. It is all about COPD and diagnoses.
A pulmonary function test (PFT) is but one aspect of diagnostic testing that will enable the physician to provide you with a definitive diagnosis.
Have you been told you have COPD?
Wishing you well,
Leon (site moderator COPD.net)
