I had a good experience with Quest recently. I made an account blind, then signed up for my appt online too. Got a link to sign in when I arrived. Then I got a text telling me it was time to come in. Only 4 people allowed in the waiting room at once (and there was one other person only), and they called me as soon as I stepped in.
The phlebotomist was masked, and had also had first dose of vaccine. This was first week of January.
