What this test is
The hemoglobin A1c test measures the percentage of your hemoglobin that has glucose attached to it. Because red blood cells live about three months, this test reflects average blood sugar over that period. It is not a substitute for daily glucose monitoring but provides a longer-term picture.
What it measures
- Hemoglobin A1c — Reflects average blood glucose over the previous two to three months.
- Estimated average glucose — A calculation that translates A1c into an average blood sugar level.
What the test involves
A small sample of blood is collected, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to help diagnose diabetes or prediabetes, or to monitor how well a diabetes treatment plan is working. It is also sometimes used as part of a routine health check.
Preparation
Preparation instructions can vary, so follow the specific instructions provided by the collection lab. In many cases, no fasting is required, but always confirm with the lab before your appointment.
How results are reported
Results are typically reported as a percentage, and your clinician will interpret them in the context of your overall health. Reference ranges can differ between laboratories, so always discuss your results with your healthcare provider.

Orders are handled confidentially: your information is kept private and results are delivered through a secure portal. Because individual collection sites differ, double-check the lab's own instructions on preparation, timing, and cost.
