Hemoglobin A1c (Glycated Hemoglobin) with probe-based measurement

Why This Test Matters for You

Your body’s blood sugar levels fluctuate daily, but this test provides a snapshot of your average blood sugar over time. It’s a key tool for managing diabetes or prediabetes, as it reflects how well your body is handling glucose (sugar) over months rather than just recent spikes or drops.

How the Test Works

Blood is drawn from a vein, typically in your arm. The sample is then analyzed to measure the percentage of your red blood cells that have sugar attached to them. This percentage is your HbA1c level, which doctors use to guide treatment decisions.

What Your Results Mean

An HbA1c result is expressed as a percentage. While exact reference ranges vary by lab and individual health, higher levels generally indicate poorer long-term blood sugar control. For example, levels above 7% may suggest higher risk for complications like nerve damage or kidney disease.

Common Reasons for Testing

Doctors order HbA1c tests to diagnose diabetes, monitor diabetes management, or screen for prediabetes. It’s often done annually for people with diabetes but may be checked more frequently if your blood sugar goals aren’t being met.
