Time for another blood test for coumadin

Blood testing time again. Seems like the vampires are always after my dad. I don't understand why they can't make an at home testing machine for coumadin levels that is like the blood sugar checkers for diabetics. You could even have it upload to a computer so you can send the results to the doctor's office.

My theory - it has not been done because then the doctors no longer make $150 a visit to poke a guy with a needle and watch a machine spit out a number in under a minute. Takes about ten minutes to take dad's coumadin level count, pulse, and blood pressure. With a home blood pressure and pulse deal (like he already has) and a machine to test the coumadin level ourselves we could save a 3 hour trip to the doctor (not counting the 2 hours it takes to get dad ready or whatever length of time is spent in the waiting room).

But then if the doctor can see 6 patients an hour and charge $150 a pop to take their coumadin level that makes the doctor's office $900.00 an hour just for poking someone with a needle and taking their blood pressure, huh?
