HbA1c: Your 3-Month Sugar Snapshot

Unlike a single sugar reading, HbA1c shows your average blood sugar over three months. Here is what the numbers mean.

HbA1c measures how much sugar is attached to your red blood cells. Because these cells live about three months, the test shows your average sugar over that time.

Reading the result

Below 5.7% is normal, 5.7% to 6.4% is prediabetes, and 6.5% or above suggests diabetes. Your doctor will confirm with other tests.

No fasting needed

HbA1c can be done at any time of day, which makes it easy to add to any home collection.
