I used my Protime yesterday to do my monthly test. The first time I tried it I got an "INR too low, try again and if 2nd test repeats this see your doc immediately." message. I tried it again and it worked fine. I'm curious, what is the cause of this message ? Is there anything I can do to prevent it in the future ? Is it due to a faulty cuvette ? Would appreciate hearing from QAS
