@jeremycherfas Glucometers have control fluid which you can use to verify the meter is working. That said, the US FDA guidelines for accuracy say that +/- 20% of the actual value is considered acceptable. Which means both of these meters could technically be accurate as the results between them vary by just over 20%.
