what is a a1c number

The A1C number (also known as HbA1c or hemoglobin A1C) is a blood test that measures your average blood sugar levels over the past 2 to 3 months. It is expressed as a percentage and is used to diagnose and monitor diabetes and prediabetes.

Here’s what the A1C ranges mean:

A1C Percentage Diagnosis

Below 5.7% Normal
5.7% - 6.4% Prediabetes
6.5% or higher Diabetes

For people with diabetes, the A1C goal is typically below 7%, but this may vary based on individual health conditions. The A1C test is a key tool in managing diabetes and preventing complications.
