Type of blood test that measures your average blood sugar levels over the past 3 months:

The type of blood test that measures your average blood sugar levels over the past 3 months is called the Hemoglobin A1C test.

Here are the steps:

1. A healthcare professional will draw a small amount of blood from your arm. This is usually done at a diagnostic lab or your doctor's office.

2. The blood sample is then sent to a lab for analysis.

3. The Hemoglobin A1C test measures the amount of sugar attached to the hemoglobin in red blood cells, which carry oxygen from your lungs to the rest of your body.

4. The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached, which can be determined by this test.

5. The A1C test result is reported as a percentage. A normal A1C level is below 5.7 percent. Anything above that could indicate prediabetes or diabetes.

6. The A1C test is effective because it gives a picture of your average blood sugar levels over the past 3 months. This can help your doctor to determine how well your diabetes management plan is working.

Remember, it's important to discuss your test results with your doctor to understand what they mean for your health.
