what is glycosylated haemoglobin test

The glycosylated hemoglobin test, also known as the HbA1c test or A1C test, is a blood test that measures your average blood sugar (glucose) levels over the past 2 to 3 months. It is commonly used to diagnose prediabetes and diabetes, as well as to monitor how well your diabetes is being managed.

How It Works:

• Glucose in your bloodstream attaches to hemoglobin, a protein in red blood cells.
• The A1C test measures the percentage of hemoglobin that is coated with sugar (glycated).
• Since red blood cells regenerate every 3 months, the test reflects your average blood sugar levels over that period.

A1C Results:

• Normal: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or higher

Why It’s Important:

• It provides a long-term view of blood sugar control, unlike daily glucose tests that only show a snapshot.
• It helps healthcare providers adjust treatment plans for diabetes management.

Things to Note:

• Certain conditions like anemia, kidney disease, or blood disorders can affect A1C accuracy.
• No fasting is required for this test.
