Two HbA1c POC methods
In a 2009 issue of Annals of Clinical Biochemistry, a study takes on two Point-of-Care HbA1c devices using two different reference methods. Both POC methods are standardized to the IFCC reference system and aligned to DCCT standards via the National Glycohemoglobin Standardization Program (NGSP). Both reference methods are also standardized against the IFCC reference method and traceable to DCCT and NGSP. If everything is standardized and traceable, there can't be any problems, right?
