I don't know whether you've been told that lab tests are currently impractical or whether you're just assuming, but if it's the latter, I would definitely ask before assuming that they're impractical. Medical professionals are better equipped to keep you safe than your local supermarket, and it may be that the local sleep lab is nowhere near places treating covid patients. I haven't heard this specifically about sleep labs, but I've heard this from friends who were putting off a few other medical procedures and were advised not to by doctors. It's at least worth calling the sleep lab and finding out what protective measures they're taking. It may be that you're well-informed already and it really is impractical, in which case I hope I didn't offend you. It's just that my impression is right now a lot of people are putting off treatment unnecessarily due to covid concerns.
