So I had posted my pft results from November (done by pulmonologist) where basically fev1 was 85%, fvc was 100% and fev1/fvc was 65%. Well had test done yesterday at allergy doctor on portable unit and those results were much lower. Fev1 was only 66%, fvc was only 80% and fev1/fvc of 64.25%. I looked back and saw I had some lower numbers on previous tests from her office before the November one. I am seeing new pulmonologist next week and I'm sure he/she would another one at the hospital pulmonary lab. My question is should I put too much stock in test results yesterday done on portable unit or wait to see what following pft results show from actual pulmonary clinic?
