Glucose Tolerance Test – This measures your blood sugar before and after you drink a liquid that contains glucose. You’ll fast (not eat) overnight before the test and have your blood drawn to determine your fasting blood sugar level. Then you’ll drink the liquid and have your blood sugar level checked 1 hour, 2 hours, and possibly 3 hours afterward.
How do they test for type 2 diabetes?
Diagnosis – Type 2 diabetes is usually diagnosed using the glycated hemoglobin (A1C) test. This blood test indicates your average blood sugar level for the past two to three months. Results are interpreted as follows:
Below 5.7% is normal.5.7% to 6.4% is diagnosed as prediabetes.6.5% or higher on two separate tests indicates diabetes.
If the A1C test isn’t available, or if you have certain conditions that interfere with an A1C test, your doctor may use the following tests to diagnose diabetes: Random blood sugar test. Blood sugar values are expressed in milligrams of sugar per deciliter (mg/dL) or millimoles of sugar per liter (mmol/L) of blood.
Less than 100 mg/dL (5.6 mmol/L ) is normal.100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes.126 mg/dL (7 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
Oral glucose tolerance test. This test is less commonly used than the others, except during pregnancy. You’ll need to fast overnight and then drink a sugary liquid at the doctor’s office. Blood sugar levels are tested periodically for the next two hours. Results are interpreted as follows:
Less than 140 mg/dL (7.8 mmol/L ) is normal.140 to 199 mg/dL (7.8 mmol/L and 11.0 mmol/L ) is diagnosed as prediabetes.200 mg/dL (11.1 mmol/L ) or higher after two hours suggests diabetes.
Screening. The American Diabetes Association recommends routine screening with diagnostic tests for type 2 diabetes in all adults age 35 or older and in the following groups:
People younger than 35 who are overweight or obese and have one or more risk factors associated with diabetes Women who have had gestational diabetes People who have been diagnosed with prediabetes Children who are overweight or obese and who have a family history of type 2 diabetes or other risk factors
How did you find out you had diabetes?
Often, the first time a person knows they have type 2 diabetes is after a routine blood test, possibly for another condition. If symptoms occur, they include an increased need to urinate, thirst, fatigue, blurry vision, and feeling hungrier than usual.
What happens if diabetes goes untreated?
Costs and Consequences is a blog series examining the health care burden of not treating diseases. Too often, the rhetoric focuses solely on the cost of medicines and disregards the adverse societal and economic impacts of not treating diseases. Stay tuned for the next post in the series and be sure to share your thoughts in the comments section below.
Diabetes is a leading cause of death in the United States and its prevalence is rising at an alarming rate. Every 30 seconds a new diabetes case is diagnosed, with almost 2 million Americans newly diagnosed each year. Currently, more than 29 million people – one in 10 American adults – have diabetes. If trends continue as many as one–in-three Americans could face the disease by 2050.
Diabetes is a complex, chronic condition that requires consistent medical care and treatment to help control blood sugar levels. If left untreated, diabetes can lead to devastating complications, such as heart disease, nerve damage, blindness, kidney failure and amputations.
- And the risk of death for adults with diabetes is 50 percent higher than for adults without diabetes.
- The cost of not treating diabetes is detrimental to the patient, and also to society.
- According to the American Diabetes Association’s report, Economic Costs of Diabetes in the U.S.
- In 2012, the total estimated cost of diabetes in 2012 was $245 billion – a 41 percent increase since 2007.
This includes $176 billion in direct medical costs and $69 billion in reduced productivity, such as increased absenteeism, reduced productivity while at work and lost productivity due to early mortality. And people with diabetes, on average, have medical costs twice as high as for people without diabetes. These costs are unsustainable and underscore the need to control diabetes with a proper treatment plan, including diet, exercise and medications. Adherence to treatment is especially critical as improved adherence to diabetes medications could result in over 1 million fewer emergency room visits and save $8.3 billion annually.
How do I know if I have diabetes without going to the doctor?
– Type 1 diabetes is usually diagnosed in childhood. Early symptoms often include unintentional weight loss, bedwetting, and flu-like symptoms. Type 2 diabetes is more likely to be diagnosed in adulthood. Early symptoms can include extreme thirst, frequent urination, and slow wound healing.
- Often, symptoms of untreated diabetes get worse and are either mild or unnoticeable in the early stages.
- A diabetes diagnosis can be confirmed with one or more blood tests.
- Talk with your doctor if you believe you have diabetes.
- Getting on top of your condition and managing it effectively is key to controlling your symptoms and preventing more serious health problems.

Does a diabetes test hurt?
/ Blog / Diabetes Knowledge / Five tips for how to avoid pain when checking your blood
Measuring your blood sugar “sticks” to diabetes like butter to bread. And even in these times of CGM (Continuous Glucose Monitoring), we can’t avoid pricking our fingers from time to time in order to manage our blood sugar levels. Measuring your blood sugar shouldn’t hurt too much.
- However, many people with diabetes complain about it hurting, or even about an unpleasant and unsightly development of calluses at their fingertips.
- But it doesn’t have to be this way if you keep an eye on a couple of things while measuring.
- I myself grew up with diabetes.
- Back then, over 20 years ago, lancing devices resembled rather a guillotine.
Or a steel lancet got simply rammed into your finger. How deep the needle or lancet went in was truly a crapshoot. Ouch! When I take a close look at my fingers these days, I have to admit: all is well! No calluses, no “bullet holes”. Neither incrusted nor pricked all over or reddened.
Unfortunately, these days patients rarely receive training on how to best measure their blood sugar levels, when it could be such an easy-peasy thing to do. You really just have to consider a few things: 1. The Lancing Device Nowadays’ lancing devices all work the same way in principle: Almost every device offers the function of adjusting the depth of the needle pricking your finger.
However, make sure to start with a light setting and work your way towards the correct penetration depth. The smallest number on the scale is the setting with the lowest penetration depth. There are also special devices/products on the market that are specifically designed to hurt less e.g. 
2. WHERE you place your lancing device Let me tell you a secret: after all, there’s no hocus-pocus to it. Use the SIDE of your finger for finger pricking! Never use the center of your finger. If you place the lancing device on the side of your finger, you’ll feel that poke much less than if you use the center of your finger. 
3. Rotation It can be super easy to fall into a pattern of testing in the same spot over and over. However, rotating spots is key to avoid those pesky callouses! Also, did you know you can test on more places than just your fingertips? Many people choose to test on their forearms or palms as well.
- Having more options can definitely help to rotate spots more consistently.
- HOWEVER, it is important to have all the information before switching to new testing sites, click here for some more information.
- By the way: make sure to avoid pricking thumbs and index fingers as they are most commonly used to touch and feel.
And while you’re at it, know that it won’t hurt to have your fingers checked out by a doctor on a regular basis.4. Changing your lancet When people say “did you change your lancet recently?” they are not just asking this for no reason. Changing your lancet regularly can actually drastically decrease the amount of pain you feel when pricking yourself.
- The lancets become dull very quickly and trying to collect a sample with a dull lancet is like trying to cut vegetables with a butter knife, painful and more difficult than it needs to be! 5.
- Warming up your hands Have you ever tried to test your blood while your hands were cold? It is usually much more difficult to collect a sample and more painful as well.
Try to warm up your hands by rubbing them together, running them under hot water or sitting on them for a few minutes, it could make all the difference! Do you have any other tips in stock which might help fellow people with diabetes to keep their “velvet paws”? If so, please feel free to post your personal finger pricking tips in the comment section below so we all can keep ourselves in “top-notch condition”!
