More than 100 million Americans are living with abnormal blood sugar. Is it possible that you could be one of them? A simple A1c screening blood test shows when levels are too high. Elevated blood sugar means higher risk for diabetes.
A glycated hemoglobin, or hemoglobin A1C, test (HbA1c) is one screening test that checks blood sugar levels. Results show how much sugar is in the bloodstream over time. Testing is accurate since values are not affected by acute illness or stress. A1c screening is recommended for certain populations, including overweight adults and those with other risk factors.
Those thinking about blood sugar testing or wondering about risk factors should talk to their doctor. Here are some common questions about diabetic screening and A1c testing.
The A1c test can detect diabetes because it measures how much sugar, called glucose, is found in red blood cells. The red blood cells give a “glycemic history” of the past 120 days.
Everyone has sugar in their blood. But diabetics have higher levels. Blood sugar that is too high leads to cell and tissue damage.
When someone is diagnosed with diabetes, their doctor will also use the A1c test to monitor how the disease is being controlled.
A1c readings are measured in percentage. Here is what A1c results mean.
Higher blood sugar levels cause greater A1c values, and they equal greater risk for diabetes.
Early detection is key in diabetes because early treatment can prevent serious complications. When a problem with blood sugar is found, doctors and patients can take steps to prevent permanent damage to the heart, kidneys, eyes, nerves, blood vessels, and other vital organs.
Here are the current recommendations for A1c screening.
The CDC suggests A1c screening to know a baseline for:
They further recommend that any woman who has ever had gestational diabetes should have an A1c check every three years even if results are normal.
The USPTF also says that adults over age 45 should be checked for diabetes using the A1c test. Furthermore, it recommends repeat testing every three years.
The ADA also recommends the A1c test, or other diabetic screening, for all adults at age 45 and over. Additionally, it advises overweight individuals with one or more risk factors to be screened, regardless of age. If results are normal, repeat screening is recommended every three years or less.
How to Get an A1C Test
If you meet some of these guidelines, you might be wondering how you can get a screening test.
A primary care doctor or other licensed provider can order this common blood test. Results take as little as a few business days.
Those who do not have a doctor to order the test, can still get this valuable screening. An online doctor or virtual physician can help. Telemedicine providers work with laboratory partners to treat patients without unnecessary trips to an office.
An online physician sends referrals and lab orders just like a brick-and-mortar doctors office. After going to a lab for blood work, virtual doctors offices schedule follow up video visits to go over the results, answer questions, and discuss treatment plans.

Stefanie:
Welcome, everyone! Thank you for joining us today.
My name is Stefanie and I'm part of the team here at MyVirtualPhysician. We are a direct to consumer, multi-specialty, telemedicine provider operating in multiple states.
It is Talk Tuesday and we are back with our weekly educational series, talking with our experts, exploring some common healthcare concerns that we see, and hopefully answering some questions you may have.
Today our physician expert is Dr. Daniel Kessler, Primary Care Physician, and one of our telemedicine providers. We are talking about a topic affecting one in ten Americans, Diabetes.
Dr. Kessler, thank you for joining us today.
Stefanie:
Let’s start by talking about Diabetes statistics. According to the American Diabetes Association, in 2018, 10.5% of Americans were estimated to have diabetes and about one-fifth of those were undiagnosed. Those are pretty significant numbers. Should people be concerned about diabetes?
Dr. Daniel Kessler:
Well that depends. We know about risk factors that can increase the likelihood of getting Type II diabetes. The CDC says you’re at risk for developing type 2 diabetes if you:
If you have non-alcoholic fatty liver disease you may also be at risk for type 2 diabetes.
So for individuals with risk factors, there should be some concern or at least awareness.
Stefanie:
So let’s talk about early detection. Why is it important? Why is early detection key in diabetes?
Dr. Kessler:
Early detection is key in diabetes because early treatment can prevent or at least slow serious complications. When a problem with blood sugar is found, doctors and patients can take effective steps to prevent irreparable damage to the heart, kidneys, eyes, nerves, blood vessels, and other organs.
An article in the Current Opinion in Endocrinology, Diabetes and Obesity journal recognized that there are many reasons why earlier detection of diabetes could be of benefit to the individual and the healthcare system, because it creates the opportunity to treat the high blood sugar.
Furthermore, undiagnosed diabetes is often associated with potentially-preventable, costly complications. ER visits and hospital stays can be expensive!
The base estimated cost of living with diabetes is around $9,600 per year. This includes prescription medications, diabetic testing supplies, doctors appointments, and routine care. This cost will be higher for uncontrolled or unmanaged diabetics who more care, more medications, more doctors appointments. Early detection can save thousands of dollars.
Stefanie:
So Dr. Kessler, for our listeners who may not be familiar with diabetes, can you tell us what a diagnosis of diabetes means? What is diabetes?
Dr. Kessler:
Sure, Diabetes is a metabolic disorder in which your body is not able to efficiently turn the food you eat into energy, leaving sugar to build up in the bloodstream. This creates two problems: the cells are not getting the sugar energy they need, and the sugar is accumulating in the blood. High blood sugar, known as hyperglycemia, causes damage to many tissues and organs of the body. This is why diabetes is a serious condition that can be dangerous.
Normally when you eat, your body breaks food down into glucose. As your blood glucose level rises, the pancreas releases insulin. Insulin is a hormone that tells body cells to let the glucose inside.
In diabetes, either your pancreas does not make insulin correctly, or your body cells do not react to the insulin the way they should. This means that the glucose stays in the blood, which is why diabetics experience high blood sugar, also known as hyperglycemia. Over time, hyperglycemia can damage nerves and blood vessels.
Stefanie:
I understand. And how do doctors know that the pancreas is not making insulin right or the body cells not reacting to the insulin?
Dr. Kessler:
Well, a blood test can determine if a person has diabetes. There are two tests commonly used.
A glycated hemoglobin test, known as a hemoglobin A1c (HbA1c) test, measures the glycated form of hemoglobin to determine the three month average of blood sugar. This blood test takes about a minute to perform, and results are generally available in two to three days. A normal HbA1c is below 5.7%. Prediabetes is 5.7 to 6.4%. A result of 6.5% or more is classified as diabetic. Another test doctors use to detect diabetes is a fasting blood glucose, or fasting blood sugar (FBS), test. This blood test measures the basal (base) sugar levels of the blood. Testing is usually performed in the morning after the patient has had nothing to eat or drink for eight hours or more. This test may take around ten minutes and results can be immediately available. A normal FBS is 70-100 mg/dl (3.9 - 5.6 mmol/L). An abnormal fasting blood sugar test may be repeated by the doctor or additional tests may be performed for confirmation of the abnormal blood sugar reading.
Stefanie:
And what these tests find, high blood sugar, can it go away? Can diabetes go away, or can early diabetes be cured?
Dr. Kessler:
Diabetes is a chronic condition which means it may not go away. It is possible, however, to reverse some of the effects of diabetes, and to even go into a remission state for those with Type II Diabetes. Remission in diabetes means that your blood sugar levels are within the normal range and you have not required medication to manage your blood sugar for six months or more.
Lifestyle changes like a healthy diet, daily exercise, and weight management can improve the way your body uses insulin, and can improve the prognosis for someone diagnosed with diabetes.
Stefanie:
Thank you Dr. Kessler, you have definitely helped me to understand diabetes better and how important it is for individuals to know their risk and talk to their physician to prevent problems and even get diagnosed and treated early!I appreciate you joining us for Talk Tuesday and telling us what we need to know about early detection in diabetes. For everyone else joining us as well, this has been Talk Tuesday with MyVirtualPhysician. If you would like to talk with one of our board-certified physicians about diabetic screening or your risk, you can check out our website at www.myvirtualphysician.com. We look forward to talking with you again, and we hope you have a great week.
In 2018, about 10.5% of Americans were estimated to have diabetes. Furthermore, about one-fifth of those cases were undiagnosed. It is important that individuals know their risk, and talk to their doctor about screening when it comes to diabetes. So, why is early detection key in diabetes?
Early detection is key in diabetes because early treatment can prevent serious complications. When a problem with blood sugar is found, doctors and patients can take steps to prevent permanent damage to the heart, kidneys, eyes, nerves, blood vessels, and other vital organs.
With simple tests for early detection, patients can make changes to reverse diabetes and even go into remission. Read on to learn more.
Diabetic care often focuses on treatment of the condition. While treatment is important, early detection increases the potential for effective changes early in the disease process.
An article in the Current Opinion in Endocrinology, Diabetes and Obesity journal recognizes that there are many reasons why earlier detection of diabetes could be of benefit to the individual and the health system, because it creates the opportunity to treat the high blood sugar and the risk factors for heart disease that often show up with diabetes. Individuals who don't know that anything is wrong may suffer long-term effects such as cardiovascular disease and stroke.
Furthermore, undiagnosed diabetes often results in potentially preventable, costly complications. Hospital stays could be avoided if patients are aware of their illness and work to manage it.
Diabetes can be expensive. The estimated cost of living with diabetes is around $9,600 per year. This covers prescription medications, diabetic testing supplies, doctors appointments, and hospital care. Medical expenses rise drastically when emergency room visits are needed for unmanaged diabetic complications.
Diabetes is a disease in which your body is not able to efficiently turn the food you eat into energy. Sugar then builds up in the bloodstream. Therefore, two problems arise: the cells are not getting the energy they need, and sugar is accumulating in the blood. High blood sugar, known as hyperglycemia, causes damage to tissues and organs of the body. That is to say, this is why diabetes is a serious condition that can be dangerous.
Normally when you eat, your body breaks food down into sugar molecules, called glucose. After that, the particles get into the bloodstream and your blood glucose level rises, signaling the pancreas to release insulin. Insulin is a hormone that tells body cells to let the glucose inside.
In diabetes, either your pancreas does not make insulin correctly, or your body cells do not react to the insulin the way they should. As a result, glucose stays in the blood, which is why diabetics experience high blood sugar, also known as hyperglycemia. Over time, hyperglycemia can damage nerves and blood vessels.
A blood test can determine if a person has diabetes. Doctors commonly use two tests to check for diabetes.
A glycated hemoglobin test, known as a hemoglobin A1c (HbA1c) test, measures the glycated form of hemoglobin to determine the three month average of blood sugar. This blood test takes about a minute to perform, and results are generally available in two to three days. A normal HbA1c is below 5.7%. Prediabetes is 5.7 to 6.4%. A result of 6.5% or more is classified as diabetic.
Another way a provider can use a blood test to see if you have diabetes is a fasting blood glucose, or fasting blood sugar (FBS), test. This blood test measures the basal (base) sugar levels of the blood. Testing is usually performed in the morning after the patient has had nothing to eat or drink for eight hours or more. This test may take around ten minutes and results can be immediately available. A normal FBS is 70-100 mg/dl (3.9 - 5.6 mmol/L). The doctor may repeat the fasting blood sugar test or order additional tests to confirm an abnormal blood sugar reading.
Diabetes is a chronic condition which means it may not go away. It is possible, however, to reverse some of the effects of diabetes and go into a remission for those with Type II Diabetes. Remission in diabetes means that your blood sugar levels are within the normal range and you have not required medication to manage your blood sugar for six months or more.
Lifestyle changes like a healthy diet, daily exercise, and weight management can improve the way your body uses insulin and can improve the prognosis for someone diagnosed with diabetes.
Diabetes is a global health problem. Health officials expect that rates will only continue to increase. Risk factors such as family history of diabetes, obesity, and sedentary lifestyle increase likelihood that you may get diabetes and so it is important to be proactive in your health and talk to your doctor about your risk for diabetes. .
