Glycosylated hemoglobin, also known as Hemoglobin A1c (HbA1c), is a blood test that measures the average level of blood sugar (glucose) over the past 2 to 3 months. Hemoglobin is a protein in red blood cells that carries oxygen, and when glucose binds to it, it becomes glycosylated. The percentage of glycosylated hemoglobin in your blood reflects how well your blood sugar has been controlled over time.
This test is commonly used to:
- Diagnose diabetes or prediabetes: A higher-than-normal HbA1c level may indicate diabetes or a higher risk of developing it.
- Monitor diabetes management: It helps assess how well a person with diabetes is managing their condition over time, as it provides a long-term view of blood sugar control, unlike daily glucose tests.
Normal ranges:
- Below 5.7%: Normal
- 5.7% to 6.4%: Prediabetes
- 6.5% or higher: Diabetes
Unlike daily blood sugar tests, HbA1c does not require fasting, making it a convenient way to track long-term glucose control. The results help guide treatment decisions, such as adjusting medications, diet, or lifestyle to better manage blood sugar levels and reduce the risk of complications like heart disease, kidney problems, and nerve damage.
