I had both kinds done
Both were ordered by my by Drs for up coming procedures which required them
( for two separate procedures)
the one allowed me to do the swab myself

they don't seem to have rules set in stone

My question has always been why the swab at all
why not a saliva test since the masks are supposed to work

obviously saliva should carry the virus germs
I can't see the need to stick a swab up the nose to find the germs

But than the so called science behind the hoax doesn't know how to find the gkost germs!
IMHO
