HbA1c levels measured by POCT device showed a high level of agreement with standard HbA1c laboratory tests in both isCGM and conventional SMBG users.

The GMI measured by the isCGM showed a high level of agreement with HbA1c levels measured by the POCT device.

The eAG measured by the conventional SMBG systems showed a high level of agreement with HbA1c levels measured by the POCT device.

For uncontrolled DM patients, isCGM provides more personalized detailed glycemic data for a better diabetes care management plan.

Measuring HbA1c levels with a POCT device is a crucial method for diabetes screening and monitoring in daily clinic visits, especially when a rapid result is needed.
