The key difference between A1c and glucose is that A1c is the percentage of glycated hemoglobin (hemoglobin that is bound with glucose) in the blood, while glucose test is a fasting blood sugar test which is done by a glucometer.
The presence of glucose in the urine is an indication of diabetes. Measuring blood sugar can tell you whether you have prediabetes or type 2 diabetes. Prediabetes is the first stage of type 2 diabetes. Both prediabetes and type 2 diabetes are risky and can cause cardiovascular diseases too. In both cases, blood sugar levels are higher than the normal blood sugar level. There are different tests we can undergo in order to determine high blood sugar. A1c and blood glucose testing are two tests among them.
