What is an A1c: Diabetes and Prediabetes Check Up?

The A1c test measures the percentage of hemoglobin coated with glucose — reflecting your average blood sugar over the past 2–3 months. Unlike a single glucose reading, it captures a sustained pattern, making it the most reliable tool for identifying diabetes, detecting prediabetes early, and monitoring how well blood sugar is controlled over time.

Diabetes screening and diagnosis

Identifies average blood glucose at or above the diabetic threshold (6.5% or higher), providing a reliable diagnostic basis without requiring a fasting blood draw on the day of testing.

Prediabetes detection

Flags blood sugar averages in the 5.7–6.4% range — the critical window where lifestyle changes or medication can reverse course and prevent progression to type 2 diabetes.

Ongoing diabetes monitoring

Tracks how well blood sugar has been controlled over the past three months for people already diagnosed, guiding medication adjustments and helping reduce the risk of long-term complications.

Frequently asked questions

What does an A1c result actually mean?

Your A1c reflects your average blood sugar over the past 2–3 months. Below 5.7% is normal, 5.7–6.4% indicates prediabetes, and 6.5% or above indicates diabetes. It's a more reliable picture of blood sugar control than a single glucose reading.

Do I need to fast before an A1c test?

No — fasting is not required for an A1c test. It measures a 3-month average rather than your current blood sugar, so recent meals don't affect the result. You can eat and drink normally before your appointment.

Can I use this test to monitor diabetes I've already been diagnosed with?

Yes — A1c is both a diagnostic tool and a monitoring tool. People with diabetes typically check it every 3–6 months to see how well their blood sugar is controlled over time and to assess whether their treatment plan is working.

My blood sugar seemed fine on a previous test — do I still need an A1c?

A single fasting glucose test only reflects that day. A1c provides a 3-month average, making it more likely to catch patterns of elevated blood sugar that a one-time glucose check might miss — especially early prediabetes.

Who should get this test?

Anyone 35 or older, people with risk factors like excess weight, family history of diabetes, PCOS, or a history of gestational diabetes, and anyone experiencing symptoms like increased thirst, frequent urination, or unexplained fatigue.
