Hemoglobin A1C testing measures the average amount of glucose (sugar) attached to hemoglobin in your red blood cells over the past two to three months. It is ordered to screen for prediabetes and diabetes, and to check how well blood sugar is being managed over time.

What it measures

  • Hemoglobin A1C — The main result, reported as a percentage of hemoglobin that has glucose attached.
  • Estimated average glucose — A value calculated from your A1C, shown in the same units as daily glucose meters.
  • Hemoglobin variants — Some inherited hemoglobin types can affect the test; labs may note or use a different method.
  • Assay method — The laboratory technique used, which can matter when comparing results over time.

Who it is for

A clinician may order this test during a routine checkup, when screening for diabetes, or to monitor someone already diagnosed with diabetes or prediabetes.

Preparation

No fasting is usually required, and the test can be done at any time of day. Tell the lab about any recent blood transfusions, pregnancy, or conditions affecting red blood cells.

Results and what they mean

Results are reported as a percentage, often with an estimated average glucose. Your clinician interprets the number along with your history, symptoms, and other tests. This is general information only and is not medical advice; discuss your results with a qualified clinician.

Can anything make my result inaccurate?
