No, this is not some kind of weird tribute band...
Just had a letter today from my consultant saying 'really sorry but your lung function results were so weird I think there might have been a technical error, could you please come and do the tests again?' (She didn't quite put it like that but that was the gist).
There go 2 more bus fares, this had better be worth it. Anyone else ever had this? I did wonder at the time because most of the results were in the 90s (low, for me, they're usually over 100) but one was 52%! That was the one lying down, and she made me do it again sitting up to see if the machine was working properly, which it apparently was because it was much better sitting up.
So basically either I have really weird lungs or I create havoc with machines.
Just sharing really as it amused me and no-one else is going to find it amusing.
