HbA1c Conversion Chart
The HbA1c test measures how much haemoglobin in the blood has become glycated (chemically bonded with glucose).
HbA1c values have changed and are now reported as a measurement in mmols/mol instead of the percentage previously given. To make sense of the new units and compare these with old units and vice versa, use our HbA1c units converter table below.
Old unit = NGSP unit = %HbA1c
New unit = IFCC unit = mmol/mol
