I had my lung function tests done last May and then again in February. My DLCO was on the low side in both, however my FVC has declined from 125% predicted to 93% predicted. This seems like quite a drop to me. Does anyone know if this is normal or have any experience of this? Thanks!

Hi Inkedup,

Certainly the results of lung function tests can vary quite a lot and I've included a link for you on Understanding Your Breathing Test Results.

Perhaps you could approach your general practitioner or consultant and ask them to explain your FVC results a little more fully to you.

Kind regards,

HI Inked up, as Joelf says, in my experience the results of lung function tests can vary a lot between each tests - my FVC have gone down and then up and then down from one year to the next. Like you my FVC was really good the first test I had (130%), then went down to 90 something % and then back up to 120%.
