This topic will help you learn about the A1C test and how to prepare for it.
What Is the A1C Test?
The A1C test, or HbA1C test, is a blood test that provides information about the average blood glucose levels over the past three months. The A1C test can be used to diagnose type 2 diabetes and prediabetes. Additionally, it is the primary test used to manage diabetes.
Interpretation of A1C levels:
| Normal | Less than 5.7 |
|---|---|
| Prediabetes | Between 5.7 and 6.4 |
| Diabetes | 6.5 and higher |
Although the A1C test does not provide daily information, a lower A1C is associated with reduced risk of diabetes complications, such as:
- Kidney diseases.
- Diabetic retinopathy.
- Neuropathy.
- Heart and vascular diseases.
When Should You Conduct the A1C Blood Test?
The test can help your doctor:
- Identify and diagnose prediabetes.
- Identify and diagnose diabetes.
- Monitor the disease and assist in making treatment decisions to prevent complications.
It is recommended to conduct an A1C test:
- Every three months for those with diabetes.
- Every one to two years if diagnosed with prediabetes.
If you have risk factors for diabetes, consult your doctor about whether you should take the test.
To prevent type 2 diabetes, you should follow these steps:
