I had never heard of it, until I read this post sounds like your DR is being very thorough. That's a good thing.

I hope the test results are good. My mom has had tests somewhat like this by a tech and then the Dr. reads them and she gets her results right away, that's the way the appointment are set up. It beats waiting for the test results. If you can have it done in his office.

When are you having it done?

You said your oxygen levels? Do you smoke?

Hang in there, Hugs, Nikko
