The HbA1c test is a blood test that shows your average blood sugar level over the past 2â3 months.
Think of it like this: instead of just seeing what your blood sugar level is today, which fasting blood sugar test or random blood sugar test will show you, HbA1c gives a bigger picture of how things have been going over time.
It works by measuring how much sugar has attached itself to your red blood cells. Your red blood cells live for about 3 months, because of this, the test can estimate your long-term blood sugar control.
Doctors use HbA1c to:
1) Screen for prediabetes or diabetes
2) Monitor how well diabetes is being managed
3) See if treatment or lifestyle changes are working
If youâve done your HbA1c test and wondering what your number or test result means, hereâs a simple guide:
Below 5.7% â Normal
5.7% â 6.4% â Prediabetes
6.5% or higher â Diabetes
So basically, HbA1c is your âblood sugar report cardâ for the last few months.
