I think it would be worthwhile for you to have the test as well.

I got COPD from smoking, I was diagnose at the mild stage around 10 years ago. I contuinued to smoke and developed lung cancer a couple of years later. They caught it very early and were able to remove a lobe of my lung and get it all but my lung tore after surgery and I ended up with a lot less lung capacity.

You are really in pretty good shape if you can ride the bike for 30 minutes.
