I received a copy of a letter which was sent from Glencourse to my ACIO stating that RG8 screening identifies I will need spirometry testing. The letter states that in order for the ACIO to complete internal and interviewing processes, a date for this testing has not been set. It goes on, 'When you are content the applicant is ready to attend ADSC please contact...at which point the applicant will be scheduled to attend ADSC'. My questions, to any Arrser's in the know, what does spirometry testing consist of? Will this test be part of my main selection, or on a seperate occasion? Is this test a pass/fail, and if fail would this mean a deferal (again ) or an Unfit for Service ? I'm guessing the reason for this testing is a history of asthma when I was a kid, i'm wasn't too worried about this being on my RG8 as it was very, very minor and hasn't required medication for nearly ten years. What I am a bit worried about is the fact I've only just quit smoking, and do get short of breath when I run, not to the point where I can't physically move or anything, but particularly on steep hills I find myself having to stop for a few seconds to catch breath. Apart from that I'm fine, physically. My 1.5 mile run time is around 10:10 average, press ups and sit ups are no real problem. I'm not Para material yet but I in no way consider myself unfit. If anyone can answer my questions I'd be very greatful. Cheers.
