The Carlson Hemoglobin A1c (HbA1c) test measures the amount of sugar (glucose) in our blood and provides insight into our body's ability to metabolize glucose, our main source of energy. Carlon's HbA1c level reflects our average blood glucose over the past 3 months. A healthy HbA1c is below 5.7% while a level above 5.7% indicates chronic elevated glucose and warrants a discussion with a healthcare provider. Elevated HbA1c can be reduced and managed through diet and lifestyle modifications.
