How 5.9 % of HbA1c converts to mmol/mol
HbA1c (glycated hemoglobin) reflects average blood glucose over the previous 8 to 12 weeks. HbA1c is reported as a percentage (NGSP/DCCT units) on U.S. and UK reports and in mmol/mol (IFCC units) on most other European reports. Many labs now print both.
HbA1c uses the IFCC-NGSP master equation rather than a single factor. 5.9 % × 10.929 − 23.50 = 41 mmol/mol. Source: IFCC-NGSP master equation (IFCC mmol/mol = 10.929 × (NGSP% − 2.15)).
