Hemoglobin A1c (Glycated Hemoglobin) with Mass Fraction Measurement

This test measures your average blood sugar levels over the past two to three months. Your doctor may order it to screen for diabetes, check how well your current treatment plan is working, or assess your risk of developing the condition.

Your healthcare provider may order an HbA1c test to monitor long-term blood sugar control, especially if you have diabetes or are at risk for it. It’s often used to check how well diabetes treatments are working or to diagnose diabetes when blood sugar levels fluctuate.

A healthcare professional will draw a small sample of blood from a vein in your arm, usually from the inside of your elbow. The procedure takes only a few minutes, and no fasting or special preparation is needed before the test.

A small blood sample is taken from your arm, usually by a healthcare professional. The test measures the proportion of hemoglobin molecules that have sugar attached, indicating average blood sugar levels from months prior.

Your results show how well your blood sugar has been controlled over time. An HbA1c level below 5.7% is considered normal, while 5.7% to 6.4% suggests prediabetes. A level of 6.5% or higher on two separate tests usually indicates diabetes.

Results are typically reported as a percentage. While exact reference ranges vary by lab, higher percentages generally indicate poorer blood sugar control, while lower percentages suggest better control. Your results will be interpreted by your provider in the context of your overall health.

Possible results include a normal range below 5.7%, a prediabetes range of 5.7% to 6.4%, and a diabetes range of 6.5% or above. Results can also be affected by conditions such as anemia, kidney disease, or recent blood loss.

Possible results may include normal, prediabetes (pre-diabetic), or diabetes ranges, depending on your clinical needs. Your provider will discuss these with you and explain what they mean for your health.
