The Definitive Guide To Understanding How A1C Is Determined
How is A1C determined? A1C is a blood test that measures your average blood sugar levels over the past 2 to 3 months. It's an important test for people with diabetes because it can help them manage their condition and prevent complications.
A1C is determined by measuring the amount of hemoglobin A1C in your blood. Hemoglobin is a protein in red blood cells that carries oxygen. When blood sugar levels are high, glucose molecules attach to hemoglobin and form hemoglobin A1C. The more glucose molecules that are attached to hemoglobin, the higher your A1C level.
A1C levels are reported as a percentage. A normal A1C level is below 5.7%. A level of 5.7% to 6.4% is considered prediabetes, and a level of 6.5% or higher is considered diabetes.
