What is HbA1C ? #bestdiabetologistinkolathur #bestcardiologistinperambur

The HbA1c test (glycated hemoglobin) is a blood test that measures your average blood glucose levels over the past 3 months, offering a reliable tool to diagnose and monitor prediabetes and diabetes. It measures glucose that has stuck to hemoglobin, with higher levels indicating higher risks of diabetes-related health complications

Key Aspects of the HbA1c Test
  • What it Measures: The test evaluates the percentage of hemoglobin coated with sugar (glycated hemoglobin). Because red blood cells live for about 3 months, it reflects long-term, rather than daily, sugar levels
    .
  • No Preparation Needed: Unlike some blood tests, you do not need to fast (skip food) before an HbA1c test.
  • Purpose: It is used to screen for, diagnose, and monitor Type 1 and Type 2 diabetes.
  • Frequency: Individuals with diabetes may need this test every 3–6 months, though some cases may require it less frequency

  • Understanding HbA1c Results
    • Normal: Below 5.7% (below 39 mmol/mol).
    • Prediabetes: 5.7% to 6.4% (39–46 mmol/mol).
    • Diabetes: 6.5% or higher (48 mmol/mol or higher
    Benefits of the Test
    • Consistency: Unlike daily, at-home blood sugar tests, which can fluctuate with meals, the HbA1c provides a consistent average.
    • Long-Term Monitoring: It helps doctors evaluate the effectiveness of lifestyle changes and medications over time
