Hemoglobin A1c (HbA1c) with Mass Concentration Measurement

This test measures the level of a specific substance in your blood. The results give your healthcare provider valuable information about how well your body is functioning and can reveal changes that may not yet be causing noticeable symptoms.

HbA1c reflects your blood sugar levels over time because red blood cells have a lifespan of about 3–4 months. The test quantifies the percentage of hemoglobin molecules that have glucose attached, indicating how consistently your blood sugar has been within or outside the healthy range during that period.

Understanding your results can help you and your doctor make informed decisions about your health. This test may be used to check for potential health problems, monitor a condition you already have, or see how well a treatment is working for you.

Unlike a single blood sugar reading, HbA1c provides a broader picture of your glucose management, helping healthcare providers identify trends that may not be apparent from daily measurements.

A healthcare professional will draw a small sample of blood from a vein, usually in your arm, using a thin needle. The procedure takes only a few minutes, and you may feel a quick pinch. Afterward, a small bandage is placed on the site, and you can typically return to your normal activities right away.

Please note: this test is usually performed on a serum or plasma sample, depending on the protocols followed by the laboratory that analyzes your blood. Your care team will make sure the sample is prepared correctly to help ensure accurate, reliable results.

Doctors commonly order this test to help screen for certain health conditions, investigate unexplained symptoms, monitor an ongoing condition, or evaluate how well a treatment plan is working over time. It is also a routine part of many regular health checkups.

This test is primarily used to diagnose type 1 or type 2 diabetes, assess long-term blood sugar control in people with diabetes, and monitor treatment effectiveness.
