How is it that differences in readings with different equipment are not taken much notice of ? I have read of people having to go to hospital to have their inr recorded regularly. It made me think about the time between the reading and the recording as my cougachec machine gives a specific time space to record the result and if you get that wrong it just shows error . Having had a bad bleed years ago I now have my inr checked at intervals with the surgery who have now got cougachec too. Perhaps it doesn't matter too much , but it did to me. Be well and safe, Terry
