How to explain this?
Greg:
I know how frustrating comparing machines and tests can be. My husband did this for 5 months! He once did 4 tests in a row on 2 machines and got 4 different INRs. I think it's called test variability. I think it was Hank who said that you have to have confidence in your machine....and, when you do, you will rely on the test results from your machine.
When I read this post, I went back to the top of this thread and read all of the responses. I had read them before as they came in. I found alot of useful information from the varied comments made by others, including the expert, Dr. Ansell. Once again, I feel that we made the right decision in keeping the ProTime. It is, however, still somewhat frustrating to realize that regardless of how the blood is tested, the results are not exact because of measurement error tolerance. Still, I'll take home testing over lab testing any day.
With kind regards,
Blanche
