walkinlab should allow you to order and pay for a big list of tests at quest or labcorp. Although some states won’t let you because of, ya know, reasons. In which case I think it works just to change your home address to a diff state.

I think he's in England... He used the word "paternalism"... Who talks like that in Murica?
We have all the best words in murica 
Yea pretty sure my dumbass state is one of the few. Thanks for the tip!! Will try that.
How do you get the blood drawn if you're in one of the jackass states? Seems most of the phlebotomy places are connected to medical groups and won't comply.
I know there are quest and labcorp labs that will take any paying customer, and you can prepay at walkinlabs. You select the labs you want and select labcorp vs quest. But other labs are tied with specific offices so you can’t do that. I had presumed that general purpose quest and labcorps are everywhere in the US but maybe not in your area? 😬
Yep I found a nearby LabCorp and looks like I may be able to get a req via email. I worried that the blood draw center would also nanny me about which state I live in (using my, uh, "other residency address" is easy enough online for ordering the req, but labs might be a little too focused on driver's license...), but hopefully the req is enough.
Thanks!
