Can You Have High A1c And Not Be Diabetic
According to one 2009 study, 3.8% of people without a history of diabetes have an elevated A1C level . This group is more likely to have other risk factors for Type 2 diabetes and cardiovascular disease. Researchers found that the following groups were more likely to have an elevated A1C without having a diagnosis of diabetes:
- Higher C-reactive protein levels
A high A1C result might signal that there is a problem. Even a modest increase in your blood sugar, above normal levels, can increase your risk of heart disease, even when you dont have full-blown diabetes, says Dr. Bellatoni. A physician can review test results and talk to patients about risk factors and lifestyle changes to improve blood sugar levels.
Whats Considered A Normal Glucose Level
Your doctor will likely test your blood glucose levels as a screening test for diabetes during a standard yearly check-up. Additionally, many people track their glucose at home with an over-the-counter finger-prick test. When you check blood glucose , either at a doctors office or with a home finger stick glucose monitor, the results are in milligrams of glucose per deciliter of blood.
One of the most common glucose measurements is fasting plasma glucose or fasting blood glucose , and its found by checking blood glucose levels after not having any calories at least eight hours before the test. According to the American Diabetes Association , people can be classified into three categories depending on their fasting plasma glucose levels: normal, prediabetes, and diabetes. To be considered normal, fasting glucose must be under 100 mg/dl.
Of note, CGM devices measure interstitial glucose levels compared to blood/plasma glucose levels measured in the FPG tests. While interstitial glucose and blood/plasma glucose levels correlate highly, they are not precisely the same, and diagnoses are not made from interstitial measurements.
Below is a summary overview of data about 24-hour glucose trends in nondiabetic individuals wearing CGM to gain a better understanding of whats normal.
How Can I Pay For Tests And Diabetes Supplies
Medicareexternal icon, Medicaid, and most private insurance plans pay for the A1C test and fasting blood sugar test as well as some diabetes supplies. Check your plan or ask your health care team for help finding low-cost or free supplies, and see How to Save Money on Diabetes Care for more resources.
How Accurate Are A1c Tests
A1C levels rise well before the clinical onset of diabetes, making early diagnosis possible according to the 2017 Standards of Medical Care in Diabetes by the American Diabetes Association . Sometimes, however, in the early stages of diabetes, blood sugar levels are not high enough to show up as problematic. Testing environments, such as temperature in the lab, equipment used, and handling of samples, can affect the results however, this is more common in the fasting plasma glucose and the OGTT than in the A1C. Strict quality controls and advancements in testing have made the A1C test more precise than in the past, according to the NIDDK. Doctors should be aware of laboratories that use an NGSP-certified method of testing for A1C levels. The NIDDK warns that blood samples taken at home or analyzed in a healthcare providers office should not be used for diagnosis.
There are some health conditions and situations that might skew the results of the test. These include:
- Blood loss or blood transfusions
Also, the test can be unreliable for people of African, Mediterranean, or Southeast Asian descent, people with a family member with sickle cell anemia, and those with thalassemia. For those who fall into these groups, a healthcare provider might suggest a different test or a specialized A1C.
What Causes Low Blood Sugar
Low blood sugar has many causes, including missing a meal, taking too much insulin, taking other diabetes medicines, exercising more than normal, and drinking alcohol. Blood sugar below 70 mg/dL is considered low.
Signs of low blood sugar are different for everyone. Common symptoms include:
Know what your individual symptoms are so you can catch low blood sugar early and treat it. If you think you may have low blood sugar, check it even if you dont have symptoms. Low blood sugar can be dangerous and should be treated as soon as possible.
Testing Your Blood Sugar Levels At Home
Testing your blood sugar at home will help you manage your diabetes. To test at home, youll need a blood sugar meter. This can test if your blood sugar levels are too low or high, monitor the effectiveness of your diabetes medication, and help you understand how other factors such as stress or illness affect your blood sugar levels.
Your doctor will be able to recommend a device for you and help you learn how to use it. They will also recommend how often you need to check your blood sugar levels at home.
When To See A Doctor
One of the best ways to ensure your blood sugar levels are normal is to seek medical advice from a healthcare professional. Endocrinologists might be your best option as theyre qualified to diagnose and treat conditions like diabetes.
Leaving low or high blood sugar levels untreated can have serious health complications, especially if you have diabetes. This is why seeking medical advice is important.
Normal Blood Sugar Levels For School
School-aged children should have blood sugar levels that range from 80 to 180 mg/dL. Understanding how food, exercise, stress, and growth hormones can affect their blood sugar levels is important for managing their blood sugar. Here are the daily normal levels for school-aged children:
- After fasting for 8-hours
- Before a meal
- 1-2 hours after eating
Normal And Diabetic Blood Sugar Ranges
For the majority of healthy individuals, normal blood sugar levels are as follows:
- Between 4.0 to 5.4 mmol/L when fasting
- Up to 7.8 mmol/L 2 hours after eating
For people with diabetes, blood sugar level targets are as follows:
- Before meals : 4 to 7 mmol/L for people with type 1 or type 2 diabetes
- After meals : under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes

Glucose, derived from foods and body stores, is a main source of energy to the body. Some health conditions, most notably prediabetes and diabetes, are characterized by elevated levels of glucose or sugar in the blood, and blood sugar tests are used to screen for, and to monitor these disorders.
Blood sugar levels can also be checked at home, using a glucose meter or other devices. Normal ranges for laboratory blood sugar tests are the same for adults of all ages. However, recommended targets for home testing will sometimes be different for older adults.
Exercise For Gestational Diabetes
Regular physical activity is a key component of a healthy lifestyle for anyone, but its especially important for diabetes management. It can help keep your weight in check, which can help keep blood sugar levels under control. Exercise helps your body use up extra glucose without requiring additional insulin and can combat insulin resistance, according to the American Diabetes Association .
The CDC recommends aiming for 30 minutes of moderately intense exercise five days a week, but you can break it up into chunks as you see fit. It doesnt have to be too complicated. Walking is great exercise, if you dont love going to the gym or anything else, Dr. Shastri says. If you prefer biking, or swimming, or dancing, its fine to go with that. Just make sure to communicate with your healthcare team, since exercise can affect your blood sugar levels.

Normal Blood Sugar Ranges In Healthy Non
For a person without any type of diabetes, blood sugar levels are generally between 70 to 130 mg/dL depending on the time of day and the last time they ate a meal. Newer theories about non-diabetic blood sugar levels have included post-meal blood sugar levels as high as 140 mg/dL.
Here are the normal blood sugar ranges for a person without diabetes according to the American Diabetes Association:
- Fasting blood sugar : under 100 mg/dL
- 1 hour after a meal: 90 to 130 mg/dL
- 2 hours after a meal: 90 to 110 mg/dL
- 5 or more hours after eating: 70 to 90 mg/dL
Why Check Blood Sugar Levels
If you take certain medication, like insulin or sulphonylureas, checking your blood sugars is a vital part of living with diabetes. It can help you work out when you need to take more medication, when you need to eat something or for when you want to get up and move around more.
Routine checks can help you know when you might be starting to go too low or too high . Its a way of getting to know your body and how it works. It can help you and your healthcare team spot patterns too. Do you write your results down? You might find that helpful.
But importantly, it will help you stay healthy and prevent serious diabetes complications now and in the future. By complications, we mean serious problems in places like your feet and your eyes. This happens because too much sugar in the blood damages your blood vessels, making it harder for blood to flow around your body. This can lead to very serious problems like sight loss and needing an amputation.
The higher your blood sugar levels are and the longer theyre high for, the more at risk you are.

What Happens During The Test
Most people can take an A1C test at any time without preparing beforehand. However, a doctor may sometimes request that a person avoids eating or drinking for 8 hours before the test.
Women who are pregnant may need to drink a sugary beverage 1 hour before the test.
A doctor or nurse will collect a blood sample, usually from a vein in the arm or hand. They will send the sample to a laboratory for analysis.
What Are Normal Blood Sugar Level Levels Prior To And After Consuming
The normal ranges for blood glucose levels in adults who do not have diabetes before eating or fasting the range starts at 72-99mg/ dL while fasting varieties for those being treated for type 1 or type 2 diabetes range from 80 -130 mg/dL. According to the American Diabetes Association regular blood glucose levels prior to and after consuming must be 80-130 mg/dL before consuming a meal , and less than 180 mg/dL about 1-2 hours after consuming a meal
High blood glucose ranges for individuals who dont have diabetes starts at 140 mg/dL or higher while for those being dealt with for diabetes, the high variety starts at 180 mg/dL, called hypoglycemia.

Make A Note Of Your Readings
It may sound obvious, but you must record your readings. Note them down in a diary, a notebook or in your phone calendar. Some meters have software that lets you do this. You could try a diabetes app too.
You and your healthcare team can then look back over your results to see if you need to adjust your treatment.
How Does Type 1 Diabetes Affect Your Childs Body
Type 1 diabetes , sometimes called juvenile diabetes, happens when your childs body stops producing insulin, a hormone that helps convert glucose from food into energy. Without it, the body cant naturally regulate blood sugar levels. So, your child must get insulin from an outside sourceinjected by syringe or infused into the body by a device called an insulin pump. Otherwise, blood sugar levels can soar too high, which can cause a number of long-term health problems from blindness to organ and limb damage if untreated.
To make sure that blood sugar levels stay in a healthy range when your child eats, you have to take a drop of blood from a finger stick and use a device called a glucometer to test it. Each result guides how many grams of carbohydrates your child can eat, the insulin dose, or how much exercise your child needs. High blood sugar isnt the only issue. Low blood sugar can cause problems when your child has too much insulin and not enough food in the body. Its a lot to manage.

Translating Your A1c To A Blood Sugar Level
Using this easy calculator from the ADA, you can translate your most recent A1C result to an eAG or estimate average glucose level.
You can also use this translation when working to improve your A1c and achieving closer to normal blood sugar levels. If you know an A1c of 6.5 is an average blood sugar level of 126 mg/dL or a range of 100 to 152 mg/dL, then you can look at your current blood sugar results on your CGM and meter and pinpoint which time of day youre frequently higher than this range.12% = 298 mg/dL or range of 240 347 11% = 269 mg/dL or range of 217 31410% = 240 mg/dL or range of 193 2829% = 212 mg/dL or range of 170 2498% = 183 mg/dL or range of 147 2177% = 154 mg/dL or range of 123 1856% = 126 mg/dL or range of 100 1525% = 97 mg/dL or range of 76 120
Normal blood sugar levels in a person without diabetes can result in an A1c as low as 4.6 or 4.7 percent and as high as 5.6 percent.
Just a decade or two ago, it was rare for a person with type 1 diabetes to achieve an A1c result below 6 percent. Thanks to new and improved insulin and better technology like continuous glucose monitors and smarter insulin pumps, more people with diabetes are able to safely achieve A1c levels in the higher 5 percent range.
Maintain Normal Blood Glucose During Pregnancy:
Pregnant women are supposed to take more care of them because it will help in avoiding the complications during delivery. It will help in maintaining their long term health and their babies. If you are obese at the beginning of your pregnancy or have a family history of diabetes then you should get diabetes sugar levels checked. If there is no as such high risk of gestational diabetes then you can get the blood sugar test between 24 and 28 weeks of pregnancy.

- Kidney damage
- Blood vessel damage
Mild hyperglycaemia, depending on the cause, will not typically require medical treatment. Most people with this condition can lower their blood sugar levels sufficiently through dietary and lifestyle changes.
Those with type 1 diabetes will require the administration of insulin , while those with type 2 diabetes will often use a combination of injectable and oral medications , although some may also require insulin.
What Is Normal Blood Sugar
ByElizabeth Palermo31 March 2014
Blood sugar, or glucose, is an important source of energy and provides nutrients to your body’s organs, muscles and nervous system. The body gets glucose from the food you eat, and the absorption, storage and production of glucose is regulated constantly by complex processes involving the small intestine, liver and pancreas.
Normal blood sugar varies from person to person, but a normal range for fasting blood sugar is between 70 and 100 milligrams per deciliter. For most individuals, the level of glucose in the blood rises after meals. A normal blood-sugar range after eating is between 135 and 140 milligrams per deciliter.
These variations in blood-sugar levels, both before and after meals, are normal and reflect the way that glucose is absorbed and stored in the body. After you eat, your body breaks down the carbohydrates in food into smaller parts, including glucose, which can be absorbed by the small intestine.
As the small intestine absorbs glucose, the pancreas releases insulin, which stimulates body tissues and causes them to absorb this glucose and metabolize it . This stored glucose is used to maintain healthy blood-sugar levels between meals.
When there isn’t enough glucose stored up to maintain normal blood-sugar levels, the body will even produce its own glucose from noncarbohydrate sources . This process, known as gluconeogenesis, occurs most often during intense exercise and instances of starvation.

Blood Sugar Levels After Eating
Blood sugar fluctuates throughout the day, but the biggest changes happen around mealtimes. Before eating, a healthy sugar level is between 3.9-5.5mmol/L. Around 1-2 hours after eating, expect blood sugar to rise to 5-10mmol/L.
If your blood sugar doesn’t stick within these ranges, the body may have stopped regulating blood sugar effectively which can lead to prediabetes and diabetes.
Diabetes Is Diagnosed By Any One Of The Following:
Sometimes you may have symptoms of fatigue, excessive urination or thirst, or unplanned weight loss. However, often people have no symptoms of high blood glucose and find a diabetes diagnosis surprising.
