I have several different meters and I at one point tested with 3 of them and got different reading from all of them using the same blood sample. I did the control test on each and all tested accurate. I am currently using a Contour, it tested in the middle, is there, or should there be that much difference in test results? From lowest to highest there was a 70 point spread!
Hi and thanks for the question! Someone else asked me a similar question so I am attaching this article that was in Diabetes Health back in 2007 that I think will help provide some insight to your question. As always it is good to consult with your doctor if you are unsure about your readings as I am not a medical professional. I hope this helps! http://www.diabeteshealth.com/read/2007/05/07/5172/why-not-make-meter-to-meter-comparisons/
