possible copd/asthma fear

just got my results and i fear about a possible copd/asthma diagnosis. Any help appreciated.. And here are the results;

fev1: 3,88 (%92)

fvc: 5.21 (%104)

fev1/fvc: 74

fef25-75: 3.00 (%63)

doc only said i had small airway obstruction but didnt talk about anything else. Is it possible that i have copd or asthma? Any help will be appreciated...

All seems normal

FEV1 normal range 80%/120%

FVC normal range 80%/120%

FEV1/FVC ratio normal range 70%/85%

FEF normal range 50%/60% and up to 130%


Hi you haven't got copd as your lung function of 92% is in the normal range.

Small airway obstruction is COPD (or asthma).

Stage: 92% Fev1 = Mild.

You can be in the normal range and have mild COPD.

Stop smoking, get BMI acceptable, avoid colds, start exercising.. to minimise progression


Did they do a reversibility spirometry test? That is after the first set of three blows did they then give you ventolin wait a period of time and then do the test again?


They did and fef25-75 increased to 77% from 63%. No big change in fev and fvc, 3% only in fev. Today talked again with the doc and he told me that i'm not copd but rather allergic asthma. Any thoughts??



Some reading for you.

had another done today and here are the results;

fev1: 4.06 (97%)

fvc: 5.39 (107%)

fev1/fvc: 75 (93%)

pef: 10.13 (105%)

fef25-75: 3.23 (68%)

doc told me that my fev1/fvc should be over 80. (i mean around 99-100%) and fef25-75 should be over 80%. he thinks that i have asthma and only prescribed (Flutikazon + Salmeterol) inhaler. by the way i'm 33 and not much of a smoker. only smoked 3-4 years, maybe a pack per week.

Any comments? I'm really concerned about the fev1/fvc. i mean it is at 75 (93%) but why the doc thinks that it should be over 80? (around 100%)
