I had a P.E. after travelling to work in Canada. I am being tested regularly there and every time they take a phial of blood and send it away for testing. I have to visit a local doctor to get the results which is tedious and expensive.
What test machine is available to buy so I can self test and visit the doctor infrequently and only to get more warfarin. Also they didn't give me the yellow book so I don't have visible means of telling anyone I am taking warfarin
