Do I have prediabetes? What is prediabetes?
Prediabetes is the state in which some but not all of the diagnostic criteria for diabetes are met. It is often described as the “gray area” between normal blood sugar and diabetic levels. The primary test to screen for prediabetes is: The glycated hemoglobin (A1C) test. This blood test indicates your average blood sugar level for the past two to three months. It works by measuring the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level between 5.7 and 6.4 percent suggests you have prediabetes. Normal levels are below 5.7 percent.
