So our CGM has always been very close to our A1C. At yesterday's endo appt they tested the accuracy of the meter built into the Omnipod PDM and it was spot on. So if the PDM is accurate (I know historically there have been Freestyle accuracy issues), and we always calibrate the CGM with the PDM, why was his A1C a full point above what the PDM would have predicted? Damn. Frustrated and bummed.
