Diabetes is a condition in which blood sugar levels are too high. Our Glycosylated HB (HbA1c) blood test measures the amount of sugar that is attached to the haemoglobin in red blood cells, with results expressed as mmol/mol, which is the standard unit for the UK.

As red blood cells live in the bloodstream for about three months, our HbA1c test shows the average blood sugar for the past few months. Unlike a regular blood sugar test, our HbA1c test is not affected by short-term changes (e.g. a recent sugary snack). So even though you may have had high blood sugar on occasion, a good HbA1c result can show that you are controlling your blood sugar levels well. If your HbA1c result is high, it could mean you have pre-diabetes or diabetes.

Symptoms of diabetes include frequent urination, fatigue, unexpected weight loss, and feeling thirsty all the time. Diabetes can lead to further complications, including heart and kidney problems.</p><p>In its early stages, type 2 diabetes can be reversed through lifestyle changes. </p><p>Diabetes is strongly associated with obesity, poor diet, and a sedentary lifestyle.
