What Is A Normal Blood Sugar Reading For Prediabetes – You should get your blood sugar tested to know for sure if you have prediabetes or type 1, type 2, orgestational diabetes. Testing is easy and results are usually available quickly.
Your doctor will do one or more of the following blood tests to confirm the diagnosis:
The A1C test measures your average blood sugar level over the past 2 or 3 months. An A1C below 5.7% is normal, between 5.7 and 6.4% means you have prediabetes, and 6.5% or higher indicates you have diabetes.
This measures your blood sugar after a night of fasting (not eating). A fasting blood sugar level of 99 mg/dL or lower is normal, 100 to 125 mg/dL means you have prediabetes, and 126 mg/dL or higher indicates you have diabetes.
This measures your blood sugar before and after you drink a liquid that contains glucose. You will stay overnight (without eating) before the test and have blood drawn to determine your fasting blood sugar level. You will then drink the liquid and check your blood sugar level 1 hour, 2 hours, and possibly 3 hours after that. A 2-hour blood sugar level of 140 mg/dL or lower is considered normal, 140 to 199 mg/dL indicates you have prediabetes, and 200 mg/dL or higher indicates you have diabetes.
This measures your blood sugar during the test. You can take this test at any time and you do not need to fast (not eat) first. A blood sugar level of 200 mg/dL or higher indicates that you have diabetes.

If your doctor thinks you have type 1 diabetes, your blood may also be tested for autoantibodies (substances that tell your body to attack itself), which are often present in type 1 diabetes but not in type 2 diabetes .You can test your urine for ketones (produced when your body burns fat for energy), which also indicate type 1 diabetes, not type 2 diabetes.
Gestational diabetes is diagnosed using blood tests. You will probably be tested between 24 and 28 weeks of pregnancy. If your risk of getting gestational diabetes is higher (due to having more risk factors), your doctor may test you earlier. Blood sugar that is higher than normal early in your pregnancy may mean you have type 1 or type 2 diabetes, not gestational diabetes.
This measures your blood sugar during the test. You will drink a liquid that contains glucose, then 1 hour later your blood will be drawn to check your blood sugar level. A normal result is 140 mg/dL or less. If your level is higher than 140 mg/dL, you should have a glucose tolerance test.
This measures your blood sugar before and after you drink a liquid that contains glucose. You will stay overnight (without eating) before the test and have blood drawn to determine your fasting blood sugar level. You will then drink the liquid and check your blood sugar level 1 hour, 2 hours, and possibly 3 hours after that. Results may vary depending on the amount of glucose drink and how often your blood sugar is tested. Ask your doctor what the test results mean.
If your test results show you have prediabetes, ask your doctor or nurse if there is a lifestyle change program offered through the National Diabetes Prevention Program in your community. You can also search for an online or in-person program. Being pre-diabetic puts you at greater risk of developing type 2 diabetes, but joining the program can reduce your risk by up to 58% (71% if you’re over 60).
If your test results show you have type 1, type 2 or gestational diabetes, talk to your doctor or nurse about a detailed treatment plan – including diabetes self-management education and support services – and specific steps you can take to be the healthiest.

Healthcare providers use it to help diagnose prediabetes and type 2 diabetes and monitor how well your diabetes treatment plan is working.
The A1C test measures the average amount of glucose (sugar) in your blood over the past three months. The result is reported as a percentage. The higher the percentage, the higher your blood sugar levels are on average.
Glucose (sugar) comes mainly from the carbohydrates in the food and drinks you consume. It is the main source of energy for your body. Your blood carries glucose to all the cells in your body to be used for energy.
Several bodily processes help you keep your blood glucose within healthy limits. Insulin, the hormone your pancreas produces, is the main factor in maintaining healthy blood sugar.
If you have persistently elevated blood sugar levels (hyperglycemia)—and an elevated A1C result—this usually indicates diabetes. Diabetes develops when your pancreas doesn’t produce insulin or enough insulin, or your body doesn’t use insulin properly.
If you have diabetes, you should get your A1C tested two or more times a year to see how well your management plan is working. Your healthcare team will recommend exactly how often you should have this test.
If you don’t have a diagnosis of diabetes, your healthcare provider may order an A1C test if you have symptoms of the disease, including:
You can also get an A1C test to screen for type 2 diabetes if you’re at risk for the disease. Risk factors include:
The A1C test relies on hemoglobin. Hemoglobin is the part of red blood cells that carries oxygen around your body. When you have glucose in your blood, it sticks to hemoglobin. This is called glycation. The more glucose there is in your blood, the more it sticks. And it can stay there for about three months — about how long the average red blood cell lives.
The A1C test measures the average amount of glucose bound to hemoglobin over time. Because the A1C test measures glucose levels over a period of time, it provides more information about blood sugar than a single blood sugar test.
You can expect the following during an A1C test that involves a sample from your vein or a blood draw:
Blood tests are a very common and essential part of medical testing and screening. There is very little risk in having either type of A1C test. You may have slight tenderness or bruising at the site of the blood draw or finger prick, but this usually goes away quickly.
In this A1C chart, the first three rows are for diagnosing diabetes. If a person with diabetes has persistently elevated A1C results, they are more likely to develop diabetes-related complications.
The A1C test result is reported as a percentage. The number represents the fraction of hemoglobin proteins that are glycated, or hold glucose. The higher the percentage, the higher your blood sugar levels have been in recent months.
If you already have diabetes, your A1C result is a look at how well your management plan has worked over the past three months. Treatment may include oral pills, insulin, monitoring blood sugar levels, and/or lifestyle changes such as diet and exercise. Your A1C can help you and your provider determine if you need to adjust any part of your treatment plan.
It’s important to remember that your A1C (if you have diabetes) is only an average measurement of your blood sugar over several months. It is not a degree or the ultimate determinant of whether you are living a healthy life. Know that your A1C will change throughout your life and that there are steps you can take to improve your diabetes management and A1C level if needed.
Some laboratories report your A1C results as a percentage in addition to the corresponding estimated average glucose (eAG).
The eAG calculator converts your A1C percentage to the same units you use with home glucose meters (glucose meters)—milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Just like your A1C is average, eAG
