what is a1c hemoglobin
Asked by: CuriousPatient
Hemoglobin A1C (HbA1c) is a blood test that measures the average blood sugar (glucose) levels over the past 2 to 3 months. It works by measuring the percentage of hemoglobin (a protein in red blood cells) that is coated with sugar (glycated).
This test is particularly useful because it provides a long-term view of blood sugar levels, unlike daily glucose tests which only show a snapshot.
