Calculating A1c Levels in People with Diabetes

Whether you suffer from type 1 or type 2 diabetes, it is always important to know your A1c level. The normal way to find out your HbA1c or glycated hemoglobin level is to have your doctor send you to a blood lab and perform the A1c test. However, there is another way to check, you can try our easy to use online A1c calculator for quick results. Calculating A1c levels requires you to enter your average blood sugar levels, which you can find in your glucometer readings. Furthermore, average glucose levels can be found on your insulin pump that uses a CGM.

Accuracy of Calculating Your A1c Online

Since I am a type 1 diabetic (t1d) and have used the online A1c calculator, I can report that this tool is very accurate. Recently I entered my average 3 month blood glucose level from my glucometer, which was 138 mg dl. The tool gave me a 6.4% A1c result, which was exactly what my recent lab results were.


I am not saying to substitute lab A1c blood tests with an online tool, but if you cannot get to your lab, calculating A1c levels online calculator can be useful. Always remember to check your blood sugar throughout the day and manage your diabetes with diet and exercise. A glucometer is perhaps the best way to check your blood glucose (bg). However, if you use an insulin pump with continuous glucose monitor (CGM), this is great as well.
