The test measures how much glucose is attached to one's red blood cells that of course contain haemoglobin. This vital substance carries oxygen around one's body and high levels of glucose will cause impairment in the process. There is a scoring system. A healthy bloodstream that is not in any immediate danger of slipping into the diabetic zone will have an HBA1c score of under 42 millimoles per mole. Anyone who records a score of between 42 and 47 is in the pre-diabetic category and those with a score of 48 or over are classed as Type 2 diabetics. ...
