Although my most recent PFT results were normal, it is still copd. If I were to take the best FVC I blew in liters in November (4.7) and compare the fev1 I blew in liters on most recent test (3.13), this ratio is not 80% as current test indicated, but rather 67% if rounded up, so back to copd. It was only normal because FVC I blew was lower
