What is it indicated for?
Medconn Glycated Hemoglobin Test System is intended for the quantitative determination of hemoglobin A1c (IFCC mmol/mol and NGSP %) in human whole blood or hemolysate with ion-exchange high performance liquid chromatography (HPLC) using the Medconn HbA1c Assay Kit (HPLC) on the Medconn Glycated Hemoglobin Analyzer, models MQ3000 and MQ3000PT.
Hemoglobin A1c measurements are used as an aid in diagnosis of diabetes, as an aid to identify patients who may be at risk for developing diabetes mellitus, and for the monitoring of long-term blood glucose control in individuals with diabetes mellitus.
