Hemoglobin A1c (HbA1c) with MPG
HbA1c, also known as glycated hemoglobin, measures the amount of hemoglobin A1c in the blood. Since red blood cells (RBCs) live for approximately three months before being recycled by the body, the HbA1c test provides information about a person's blood sugar control over the last two to three months. It’s used to help diagnose and monitor metabolic syndrome (pre-diabetes) and diabetes. In addition to providing the HbA1c number, this test also reports the mean plasma glucose (MPG) level, an estimate of your blood sugar over time.

HbA1c provides a better estimate for blood sugar control over time than routine blood glucose testing. Multiple studies in several countries have confirmed that a higher HbA1c level is an independent risk factor for diabetes complications, including cardiovascular disease (CVD), kidney damage (nephropathy) and eye damage (retinopathy).
The American Diabetes Association (ADA) has recommended that people with stable diabetes get their HbA1c tested twice a year. For people having difficulty controlling their blood glucose, but who do not have diabetes, the ADA has recommended they get their HbA1c tested quarterly. Interpretative ranges are based on ADA guidelines.
