HbA1c tests are critical for monitoring diabetes, but misconceptions about their reliability persist. Neurologist Dr. Sudhir Kumar addressed these myths, stating that while extreme hyperglycemia can theoretically distort HbA1c results, this is rarely clinically relevant. Instead, he highlighted that conditions affecting red blood cells, such as iron deficiency anemia and hemolysis, are more significant factors leading to inaccurate readings. Consultant Dietitian Kanikka Malhotra reinforced that HbA1c reflects average blood sugar over approximately three months and is influenced by the lifespan of red blood cells. Patients experiencing discrepancies between their HbA1c results and daily glucose readings should consult their doctors for further testing, such as fasting blood glucose or continuous glucose monitoring. This ensures a comprehensive understanding of their diabetes management.
