Some vets have the capability to do Coggins testing in house, so the results would be back the same day. I realize it's a bit late for it this time, but you might call around and see.
My vet can do a stat one day test. For an extra 20 dollars:')
None of them around me do the lab work in-house. They send it out. I'll just have to wait until next time.
Thanks for the suggestion though.
