Getting realtime results can result in a lower A1C on your next visit.

The A1C test is also called glycated hemoglobin, HbA1c, or glycosylated hemoglobin. A1C provides an indication of your average blood glucose for the past 2-3 months. Hemoglobin is part of the red blood cells and binds to glucose. The A1C complex is formed when the glucose in the blood binds irreversibly (glycates) to hemoglobin. The higher the glucose level in the blood, the more that binds to the hemoglobin. Therefore, A1C values are proportional to the amount of glucose in the blood. The A1C result is in percentage (%) units and reflects the percentage of the hemoglobin that is glycate1.

Hemoglobin remains glycated for the lifespan of the red blood cell, about 90-120 days. Therefore, the A1C test reflects an average blood glucose control for the past 2-3 months. Mean blood glucose of the 30 days prior to the A1C test contributes to 50% of the A1C value2 Fasting plasma glucose contributes more to A1C results in patients with poorly controlled diabetes. In satisfactory to good control of diabetes, postprandial glucose is the predominant contributor.3,4

Testing Made Easy

  • The ADA recommends that healthcare professionals use A1C point-of-care testing for timely decisions on therapy changes
  • Giving diabetes patients on-the-spot feedback on their A1C number may result in a 1% point reduction in their A1C
  • A 1% point reduction in A1C may lower the risk of complications by up to 40%*5
* in non-pregnant adults with type 2 diabetes.
