What is an A1C test?
An A1C test is a blood test that shows your average blood sugar over about the past three months. It measures how much sugar is attached to hemoglobin, the protein in red blood cells. You do not need to fast for an A1C test, which makes it a simple way to check for prediabetes and type 2 diabetes.
A blood glucose test measures the sugar in your blood at the moment of the test. A fasting glucose test is done after at least eight hours without food. Your provider at Texas Primary Care Associates chooses the right test and may repeat it to confirm a diagnosis.
- A1C test with no fasting needed
- Fasting or random blood glucose tests
- Prediabetes and type 2 diabetes screening
- Same-day plan if your numbers are high

Who should get a blood sugar test?

What do A1C and blood sugar results mean?
These are the standard ranges used to diagnose prediabetes and diabetes in adults who are not pregnant. A diagnosis is usually confirmed with a second test.
| A1C test | Fasting glucose test | Oral glucose tolerance test | |
|---|---|---|---|
| What it measures | Average blood sugar over about 3 months | Blood sugar after at least 8 hours without food | Blood sugar 2 hours after a sweet drink |
| Fasting needed | No | Yes | Yes |
| Normal | Below 5.7% | 99 mg/dL or lower | Below 140 mg/dL |
| Prediabetes | 5.7% to 6.4% | 100 to 125 mg/dL | 140 to 199 mg/dL |
| Diabetes | 6.5% or higher | 126 mg/dL or higher | 200 mg/dL or higher |
Why blood sugar testing matters
Millions of adults have prediabetes or type 2 diabetes and do not know it, because high blood sugar often causes no symptoms at first. Over time, high blood sugar can damage the heart, kidneys, eyes and nerves. Testing finds the problem early, when lifestyle changes and treatment work best.
How to prepare for your test
- For an A1C test, eat and drink as usual
- For a fasting glucose test, have nothing but water for at least 8 hours before
- Take your usual medicines unless your provider tells you otherwise
- Bring a list of your medicines and any home blood sugar readings
If your results show prediabetes
Prediabetes means your blood sugar is higher than normal but not yet in the diabetes range. Losing a modest amount of weight and being active most days can lower your chance of developing type 2 diabetes. Your provider can recheck your numbers, help with a plan and discuss medical weight loss for prediabetes.

If your results show diabetes
If testing confirms type 2 diabetes, the same team can start your treatment plan, including lifestyle steps, medicine if needed, and checks for your eyes, feet, kidneys, blood pressure and cholesterol. Learn more about diabetes management at our clinic.

Call (903) 230-9811What is an A1C test?
An A1C test is a blood test that shows your average blood sugar over about the past three months. An A1C of 5.7% to 6.4% means prediabetes, and 6.5% or higher on two tests means diabetes.

How often should I be tested for diabetes?
If your results are normal, many adults are retested about every three years. If you have prediabetes or other risk factors, your provider may recommend testing every year.
What are the early signs of high blood sugar?
Common signs include feeling very thirsty, urinating often, blurry vision, tiredness and cuts or sores that heal slowly. Many people have no symptoms, which is why testing matters.
Does insurance cover diabetes testing?
Most plans, including Blue Cross Blue Shield, UnitedHealthcare, Medicare and Ambetter, cover diabetes testing when it is recommended. Coverage depends on your plan and risk factors, so call to verify.
