What is the acceptable hemoglobin A1C level for a non-diabetic individual?

The acceptable hemoglobin A1C level for a non-diabetic individual is characterized by a value below 5.7%. This range indicates that an individual's blood sugar levels have been well-regulated over the past two to three months, reflecting a healthy metabolic state. Values within this threshold show that there is no significant insulin resistance or glucose intolerance, which are risk factors for developing diabetes in the future.

The cutoff values for hemoglobin A1C help healthcare professionals evaluate an individual’s risk for diabetes and other metabolic disorders. For example, an A1C level below 5.7% is considered normal, while values from 5.7% to 6.4% indicate an increased risk of developing diabetes (prediabetes). Therefore, maintaining an A1C level below 5.7% is crucial for non-diabetic individuals to avoid complications associated with higher blood glucose levels.
