HbA1c

Last Updated: April 6 2021

HbA1c (glycated hemoglobin) is a biomarker of glucose metabolism — it reflects glucose levels over months. Higher HbA1c is associated with more disease progression and comorbidities in states of insulin resistance or diabetes.

Summary

Hemoglobin A1c (HbA1c) represents the percentage of red blood cells that are glycated (i.e., glucose-bound). HbA1c can give an idea of a person’s average sugar levels over the past 3 months (the approximate lifespan of a red blood cell).
