The One Drop Guide to A1C
A Numbers Game
Living with diabetes means living with numbers. Lots of numbers.
Take A1C, for example. What is A1C? The hemoglobin A1C (“HbA1C” or "A1C") blood test is used to diagnose diabetes and assess how well someone is managing their diet, food, activity, and blood glucose levels.
But what is A1C? What are the A1C ranges that define prediabetes and diabetes? What causes your A1C numbers to rise? How do you convert A1C to average blood glucose?
A1C: The Ultimate Guide
The A1C test is a blood test used to diagnose diabetes and assess how well someone is managing their diabetes. Your A1C value is a number that reflects your average blood glucose (BG) over the past 2-3 months*.
To help better understand all those numbers, we've come up with a helpful guide! In it, you can track your numbers with a detailed A1C chart and use set goals for future A1C test results.
*Red blood cells live 2-3 months, so A1C reflects the hemoglobin's exposure to glucose over that time.
