HbA1c is the measurement of glycated Hemoglobin.

Glucose can attach to Hemoglobin, forming glycated Hemoglobin

The measurement is “How much of the Hemoglobin is glycated” Which can be displayed in:

  • mmol (glycated) / mol (total)
  • A percentage (%) which is glycated divided by total

This biomarker is used to see someones average blood glucose over the last 2-3 months as red blood cells live around 120 days.
