NGSP and IFCC-derived NGSP HbA1c can be used interchangeably.
OBJECTIVE
To evaluate comparability of NGSP-certified method and IFCC-calibrated method.


METHODS
HbA1c was measured on two analyzers (n=50). Comparability was tested by Deming regression, bias estimation and Friedman test.


RESULTS
A strong correlation and good agreement between two methods was demonstrated.


CONCLUSIONS
NGSP and IFCC-derived NGSP HbA1c can be used interchangeably.
