Glycated Hemoglobin Conversion Chart

National Glucose Standardization Program (NGSP) values (%) and International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) values (mmol/mol) based on the formula of IFCC = 10.93(NGSP)-23.50. Conversions are grouped according to each percentage point on the NGSP measurement scale. IFCC-standardised values are rounded to the nearest whole number.
