HbA1c

[edit | edit source]
  • Long-term assessment of the level of glycated haemoglobin, which represents 2-3 months worth of average, but is more weighted towards the past month
  • When plasma glucose is consistently elevated, there is an increase in the non-enzymatic glycaemic history over the previous 2-3 months, because erythrocytes have an average lifespan of 120 days
  • Rough correlates:
    • Hba1c 6% = average BSL 7
    • 7% = 8.6
    • 8% = 10.2
    • 9% = 11.1
    • 10% = 13.4
    • 11% = 14.9
    • 12% = 16.5
