HbA1c, also known as glycated hemoglobin, is a blood test that reveals your average blood sugar (glucose) level over the past two to three months. This test is crucial for managing and diagnosing diabetes.
Understanding HbA1c
- How it works: Glucose, a sugar in your blood, attaches to hemoglobin (a protein in red blood cells) forming HbA1c. The higher your average blood sugar, the more HbA1c is present.
- What it measures: It doesn't show your blood sugar at a single point in time, but rather an average over several months. This provides a better picture of long-term blood sugar control than frequent single blood sugar tests.
- Uses: The HbA1c test is used to:
- Diagnose type 2 diabetes.
- Monitor blood glucose control in people with diabetes.
- Screen for prediabetes.
Interpreting HbA1c Results
- Normal levels: Generally below 5.7%.
- Prediabetes: Levels between 5.7% and 6.4%.
- Diabetes: Levels 6.5% or higher on two separate tests. (Specific ranges may vary slightly depending on the laboratory).
Note: HbA1c results should always be interpreted by a healthcare professional. They consider the results along with other factors, such as symptoms and other blood tests.
HbA1c and Diabetes Management
Maintaining a healthy HbA1c level is vital for managing diabetes. Factors influencing HbA1c levels include diet, exercise, medication, and overall health. Working with your healthcare provider to develop a personalized diabetes management plan is crucial to achieving and maintaining healthy HbA1c levels.
