The hemoglobin A1c test monitors the blood in different ways to provide a reading of an overall blood glucose without relying on a series of fasting plasma glucose assessment, according to the American Diabetes Association. The test is standardized, quick and simple, notes WebMD.
Insufficient fasting and acute perturbations, such as exercise, diet or stress, do not influence the A1c test, and it can be carried out anytime regardless of feeding or fasting. Even with optimal preparation for glucose testing, preanalytical instability affects plasma glucose values. The efficiency of the results allows individuals to take early action to control blood sugar levels, states Bayer Diabetes.
