Your doctor will have you take one or more of the following blood tests to confirm the diagnosis:
- A1C Test. The A1C test measures your average blood sugar level over the past 2 or 3 months.
- Fasting Blood Sugar Test.
- Glucose Tolerance Test.
- Random Blood Sugar Test.
- Glucose Screening Test.
- Glucose Tolerance Test.
Can I test myself for type 2 diabetes?
Type 2 diabetes screening by pharmacists – Some pharmacists offer short appointments where you can find out your risk of developing type 2 diabetes. You usually pay a fee for this service, which involves answering a series of questions. A diabetes screening test does not diagnose you and is not completely accurate.
- Instead, it can be used as a guide.
- Depending on the results from this screening, you or your loved one may be advised to seek further medical help from your local GP.
- If you don’t appear to be at risk at the time of screening, this doesn’t mean you aren’t still at risk of developing type 2 in the future.
If you later find signs of diabetes it’s worth being screened again, or being tested for diabetes. Some pharmacists offer blood tests to diagnose diabetes, but you’ll need to pay for these unlike having them through your doctor.
How to check if you have diabetes?
Tests for type 1 and type 2 diabetes and prediabetes –
Glycated hemoglobin (A1C) test. This blood test, which doesn’t require not eating for a period of time (fasting), shows your average blood sugar level for the past 2 to 3 months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. The higher your blood sugar levels, the more hemoglobin you’ll have with sugar attached. An A1C level of 6.5% or higher on two separate tests means that you have diabetes. An A1C between 5.7% and 6.4% means that you have prediabetes. Below 5.7% is considered normal. Random blood sugar test. A blood sample will be taken at a random time. No matter when you last ate, a blood sugar level of 200 milligrams per deciliter (mg/dL) — 11.1 millimoles per liter (mmol/L) — or higher suggests diabetes. Fasting blood sugar test. A blood sample will be taken after you haven’t eaten anything the night before (fast). A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it’s 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes. Oral glucose tolerance test. For this test, you fast overnight. Then, the fasting blood sugar level is measured. Then you drink a sugary liquid, and blood sugar levels are tested regularly for the next two hours. A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours means you have diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) means you have prediabetes.
If your provider thinks you may have type 1 diabetes, they may test your urine to look for the presence of ketones. Ketones are a byproduct produced when muscle and fat are used for energy. Your provider will also probably run a test to see if you have the destructive immune system cells associated with type 1 diabetes called autoantibodies.
How does type 2 diabetes begin?
Insulin resistance – Type 2 diabetes usually begins with insulin resistance, a condition in which muscle, liver, and fat cells do not use insulin well. As a result, your body needs more insulin to help glucose enter cells. At first, the pancreas makes more insulin to keep up with the added demand. Over time, the pancreas can’t make enough insulin, and blood glucose levels rise.
Does diabetes show up in routine blood test?
A simpler form of testing individuals with risk factors for diabetes could improve diabetes prevention efforts by substantially increasing the number of individuals who complete testing and learn whether or not they are likely to develop diabetes. Approximately 60 million Americans, one-third of the adult population, are pre-diabetic.
Thirty percent of these individuals will develop Type 2 diabetes in less than a decade, yet most don’t know they are at high risk for the disease. A study published in the January 2011 issue of the American Journal of Preventive Medicine reports that the hemoglobin A1c test, a common blood test that can be quickly administered in a physician’s office, accurately and easily identifies pre-diabetics.
The A1c test measures average blood glucose level over the past 8 to 12 weeks and does not require a person to return for additional testing after an overnight fast. Researchers, led by Ronald T. Ackermann, M.D., M.P.H., associate professor of medicine at the Indiana University School of Medicine and a Regenstrief Institute affiliated scientist, report that the A1c blood test, which has been routinely administered to diabetic patients for many years, can also pinpoint pre-diabetes.
- Identifying more individuals with pre-diabetes through a simple test in a physician’s office gives us a real opportunity to halt progression to the disease, which is clearly a win-win situation,” said Dr.
- If you have high blood pressure or heart disease, or multiple other risk factors such as obesity, are over the age of 45, had a past episode of diabetes during pregnancy, or have a family history of the disease, your physician can administer a simple blood test which will show if you are pre-diabetic.
If you are pre-diabetic, loosing as little as 10 to 15 pounds through diet and exercise can cut in half your chances of getting diabetes, greatly improving your health and lowering your need for health care,” said Dr. Ackermann, who is associate director of the Diabetes Translational Research Center at the IU School of Medicine and director of the Indiana Clinical and Translational Sciences Institute Community Health Engagement Program.
Fasting tests, which are currently used to screen for pre-diabetes are difficult to administer primarily because they usually require two visits to the physician’s office and because patients often forget to arrive on an empty stomach when they return for the test. The A1c test can avoid both of these problems because it can be performed on a single visit, even if a person has eaten.
It is estimated that currently only 7 percent of all Americans with pre-diabetes have been tested and are aware of their status. “Type 2 diabetes is growing rapidly with the increasing rate of obesity and has reached epidemic proportions in this country.
- Identifying pre-diabetics and halting the disease could prevent millions of individuals from developing diabetes and would avert the very high future costs of treating it.
- Lifestyle interventions in the pre-diabetic stage offer benefit not only by preventing type 2 diabetes but also by reducing cardiovascular risk factors,” said Dr.
Ackermann. In 2002, the Diabetes Prevention Program, a large clinical trial, determined that diet and exercise sharply lower the risk that a person with pre-diabetes will develop diabetes. In a 2006 study Dr. Ackermann reported that it would be cost effective for Medicare to pay for diabetes prevention at age 50 rather than to deny prevention benefits until age 65 when many individuals will have already developed the disease.
- Since that 2006 study, health insurance companies have taken a much closer look at paying for structured diabetes prevention programs as a means to improve health and to help curb the runaway costs of health care.
- In 2010, the UnitedHealth Group, a large nationwide health insurance carrier, began paying for a diabetes prevention program offered by the YMCA of the USA.
The health plans, however, only pay for this treatment when a blood test shows pre-diabetes. “Since health plans are beginning to pay for pre-diabetes treatments, doctors now have a more compelling reason to encourage patients who have risk factors to complete a screening test,” said Dr.
- The more practical A1c test could help doctors perform testing on a much larger scale than ever before.” The new study, which looked at blood test results of 1750 individuals with pre-diabetes, was funded by the Centers for Disease Control and the Robert Wood Johnson Foundation.

When should I get tested for diabetes?
In people without symptoms, testing should begin at age 45 and every three years thereafter or earlier in adults who are overweight or obese—meaning a body mass index (a measure of body fat) ≥25 kg/m²—and have any of the following other risk factors: Parent or sibling with diabetes.
What if I have diabetes without knowing?
Could You Have Diabetes and Not Know It? According to the American Diabetes Association, of the 30 million Americans who have diabetes, 7 million don’t know it. So, yes, you most certainly can have diabetes and not know it. Without treatment, diabetes can increase your risk of developing other health issues, such as kidney disease, peripheral neuropathy, or heart disease.
What are the first warning signs of type 2 diabetes?
– Type 2 diabetes is a common condition that causes high blood sugar levels. Early signs and symptoms can include tiredness and hunger, frequent urination, increased thirst, vision problems, slow wound healing, and yeast infections. Anyone who experiences possible signs and symptoms of diabetes should contact a doctor for an evaluation, especially if they have other risk factors for developing this condition.
The early detection and treatment of type 2 diabetes can improve a person’s quality of life and reduce the risk of severe complications. It is important to have a support system of people who understand what it is like to have a diagnosis and live with type 2 diabetes. Bezzy T2D is a free app that supports people with type 2 diabetes through one-on-one and live group discussions.

What age does type 2 diabetes usually start?
Healthy eating is your recipe for managing diabetes. More than 37 million Americans have diabetes (about 1 in 10), and approximately 90-95% of them have type 2 diabetes. Type 2 diabetes most often develops in people over age 45, but more and more children, teens, and young adults are also developing it.
