eAG (Estimated Average Glucose)

July 17, 2013

eAGThe hemoglobin A1C blood test gives you an average of your blood sugar over the past two to three months. People with diabetes get this test done every three to six months. According to the American Diabetes Association, an A1C of 6.5 percent or above means a person has diabetes; an A1c between 5.7 to 6.4 percent means a person has prediabetes; and an A1C of 5.7 or below is considered no diabetes. Many health care providers use this test to evaluate how one’s treatment plan is working.

Recently something called estimated average glucose, or eAG, was introduced.  This test result directly correlates with the A1C and may help one understand the A1C result better. The A1C is reported as a percentage, whereas, the eAG is reported in mg/dl. This is not to be confused with the results from self monitoring one’s blood sugar using a home blood sugar monitoring system. Self monitoring blood sugar gives a single result at one point in time. The A1C and eAG provide an average of blood sugar levels 24 hours per day.
