Hi, I am 40 years old and recently had a spirometry test for work as part of a health screening thing, its the first time I've had one. I was refered to my GP as my FEV1 was only 79%, and my fev1/fvc was 59%. I have smoked for 25 years although i gave up about 3 months ago ( not because of the result of the test).
I googled my result and everything I could find basically said I have COPD or Asthma.
The nurse at the surgery scrunched here nose up at the spirometry test results and said they mean nothing on their own and that there is a very specific way of blowing into the machine. She listened to my chest and said it was clear, and my oxygen in my blood was 98%. I asked her if she thought I had COPD and she said she didn't think so as I had no symptoms.
She has arranged for me to have another spirometry test with the Asthma doctor ( had asthma as a child) in 6 weeks, it's going to be a long wait and I'm scared as I don't see how the first test would be wrong. Two of the three blows gave very similar readings and the third was no where near the other two.
