A1c Test
The A1C test is a blood test that used to diagnose type 1 and type 2 diabetes. It is used gauge how well you’re managing your diabetes. The A1C test is also known as glycosylated hemoglobin, hemoglobin A1C, glycated hemoglobin and also HbA1c.
The A1C test result is used as an representative indication of your average blood sugar level for the past two to three months. The A1C test is specifically used to measure what percentage of the hemoglobin (protein) in the red blood cells carries oxygen and is coated with sugar (glycated). A higher A1C level indicates poor blood sugar control and a higher risk of developing diabetes complications.
A1c Test Units
Some countries, such as the UK, Australia and New Zealand, use a different set of units for measuring A1c results.
The way A1c values are reported in the US, using %, is known as the DCCT (Diabetes Control and Complications Trial) units.
The way A1c is reported in some other countries is using the IFCC (International Federation of Clinical Chemistry) units. The IFCC values use mmol/mol (millimoles per mole).
If you need to convert an A1c result from % to mmol/mol, or vice versa, use the calculator below. It will also give you the conversaion into mg/dl to compare it with your blood glucose readings and eAG results.
