Teri, I live at 5000 ft altitude near Denver... so you're saying the sleep study may not be comparable between an at-home sleep study vs an in-lab sleep study? That's quite interesting! I'll talk with my pulmonologist about that. Thanks!

I live at higher altitude in the Sleep study lab. Therefore my sleep study lab did not show my need for oxygen as did my home study. I think it depends on where you live and where the lab is located. We actually threw out my whole Sleep labs study.

That's an interesting point that I never would have considered. I live in Maricopa County in Arizona where everybody and every facility in the county is at the same low altitude...all very PH friendly.

You are so very welcome! We are all in this together!

If your insurance will cover the in-lab study, do that. Some insurance will want a home test done first. But those aren't as reliable.
