HbA1c to Average Glucose Calculator
HbA1c stands for Haemoglobin A1c, which is a blood test that measures the average level of blood sugar (glucose) over the past 2-3 months. Haemoglobin is a protein in red blood cells that carries oxygen throughout the body, and glucose can attach to haemoglobin molecules. The HbA1c test measures the percentage of haemoglobin that has glucose attached to it.
The HbA1c test is commonly used to monitor diabetes. The test can provide information about how well a person's blood sugar has been controlled over time and can help identify high blood sugar levels that may lead to complications.
This is a very brief explainer about HbA1c and its role in monitoring diabetes. We also regularly publish summaries of recent research in science and medicine relating to HbA1c and diabetes. Please follow our medical news section for these updates.
Clinical significance HbA1c levels:
Please note that the explanations below are very broad and that any diagnosis will involve your GP taking many factors into consideration, including your results and medical history...etc.
An elevated level of HbA1c can mean:
Poorly controlled diabetes.
Non-diabetic hyperglycaemia. This maybe due to e.g., Cushing syndrome, corticosteroid therapy.
Some pregnant women might experience gestational diabetes or prediabetes.
A decreased level of HbA1c can mean:
Haemolytic anaemia.
Chronic renal failure.
Treatment for diabetes may involve lifestyle changes such as diet and exercise, medications, or insulin therapy. Regular monitoring of blood sugar levels and HbA1c levels is an important part of managing diabetes and preventing complications.
Our HbA1c tests provide you with a result within 24-48 hours of samples arriving in our laboratory.
