  Glycosylated Hemoglobin (HbA1c)

Home > Calculators > Glycosylated Hemoglobin (HbA1c).
Glycosylated hemoglobin (HbA1c) is formed by the attachment of glucose to hemoglobin (the oxygen carrying protein found in red blood cells). The percentage of glycosylated hemoglobin in the blood reflects the average blood sugar levels over the preceding 2-3 months.

The calculator below can be used to estimate the average blood sugar level based on the measured percentage of glycosylated hemoglobin (HbA1c).

Enter Glycosylated Hemoglobin (HbA1c) =  


Average plasma blood glucose = mg/dl      mmol/L

Average whole blood glucose = mg/dl     mmol/L

 

FORMULAS :

  • Average Plasma Blood Glucose (mg/dl) = (HbA1c * 35.6) - 77.3
  • Average Plasma Blood Glucose (mmol/L) = (HbA1c * 1.98) - 4.29
  • Average whole blood glucose = Plasma Blood Glucose / 1.12
