Recently I used my testing machine ( my tablet won't let me type the name ) to test my I.N.R.. and the reading was 5.7. I waited 10 mins and did it again, this time it was 4.1 and 10 mins later it was 4.6. I went to my G.P.s and their machine tested me at 3.7. Clearly a problem.
I rang Roche and they said it was clearly unacceptable and the machine shouldn't be unreliable even though they accept a low element of variation. They said they would send me another free of charge and could I send the other back for investigations. Two days later I received through the post: a new machine anew pot of testing strips and a Lancet holder (I'm sure that's not what it's called but it describe it quite well). I think that's pretty good service don't you? It's not often we get such an immediate response. X
