Ok so we opened a new box/container of test strips. We attempted a calibration using the control solution and 5 strips in a row failed the calibration. Neither the test strips nor the control solution have expired. We have other test strips in other containers that passed the calibration so we are ok there, but what do we do with this container of strips? 50 test strips is 50 test strips. Do we try and get our money back from Expressscripts or do we get our money back from the manufacturer of the strips?
