Glycosylated Hemoglobin (HbA1c)
Glycosylated hemoglobin is blood glucose bound to hemoglobin. Hemoglobin A₁C (glycosylated hemoglobin A; HbA1c) is a reflection of how well blood glucose levels have been controlled for the past 3 to 4 months. Hyperglycemia in clients with diabetes is usually a cause of an increase in the HbA1c.
Normal and Abnormal Lab Values for Glycosylated Hemoglobin
- 7% or lower (good control of diabetes)
- 7% to 8% (fair control of diabetes)
- Higher than 8 % (poor control of diabetes)
Nursing Consideration
