A1C is a blood test you can get done to see the progression of atherosclerosis, the buildup of plaque in your blood vessels. The higher the number, the more plaque you have. If someone has a high A1C, doctors almost always attribute it to high cholesterol, when it’s actually blood sugar. A1C is glycated hemoglobin, and it shows the average glucose (sugar) that’s attached to the hemoglobin.
