What Is Blood Glucose
Blood glucose comes from food. As you eat, food is broken down into sugar and sent to the blood. The insulin is what helps the sugar go into the cells. Once this happens, the sugar is either used for energy or stored away.
Glucose is known as the bodys main energy source. Too much glucose in the blood, or if it is not absorbed properly, can create both short- and long-term health issues. To keep a healthy blood sugar level, its important to:
What Should I Do After I Check My Blood Glucose

- Include all of your blood glucose numbers.
- Write a comment if there is a reason the blood glucose is above or below target.
- Take your blood glucose meter with you when you are away from home.
- Know your blood glucose numbers when you call the clinic or the doctor.
- Bring your blood glucose meter and blood glucose records to all your appointments.
- Bring a list of any questions that you may have.

What Is A Finger Stick Blood Test
Blood pumping throughout your body transports a variety of essential nutrients your cells need, like oxygen and glucose. A finger stick blood test is an easy way to measure the amount of a certain substances in your blood, by making a small prick into your fingertip and collecting a blood sample into a specially designed test strip or into a thin tube for laboratory testing. These convenient, easy tests only require a small amount of blood.
Depending on the specific test being performed, a finger stick blood test can be used to measure glucose, hemoglobin A1C, ketone, lactate levels, and more.
Cgm Studies In Nondiabetic Individuals

One study from 2009 entitled Reference Values for Continuous Glucose Monitoring in Chinese Subjects looked at the glucose levels of 434 healthy adults using CGM and found the following:
- On average, their daily glucose levels stayed between 70140 mg/dl for 93% of the day, with very small portions of the day spent above 140 mg/dl or below 70 mg/dl.
- Also, their mean 24-hour glucose levels were around 104 mg/dl
- 1-hour post-meal glucose values average 121-123 mg/dl for breakfast, lunch, and dinner
- 3-hour post-meal glucose values were around 97-114 mg/dl.
- Peak post-meal values appeared to be around 60 minutes after eating.
- Mean fasting glucose was 86 ± 7 mg/dl.
- Mean daytime glucose was 106 ± 11 mg/dl.
- Mean nighttime glucose was 99 ± 11 mg/dl.
A 2010 study, Variation of Interstitial Glucose Measurements Assessed by Continuous Glucose Monitors in Healthy, Nondiabetic Individuals, looked at a healthy population of 74 individuals that included children, adolescents, and adults during daily living using CGM. This research showed that:
- Glucose levels stayed between 71-120 mg/dl for 91% of the day.
- Levels were lower than 70 mg/dl for 1.7% of the time and greater than 140 mg/dl, only 0.4% of the time.
- Mean 24-hour glucose was 98 ± 10 mg/dl.
- Mean fasting glucose of 86 ± 8 mg/dl.
Compared to the first study mentioned, these healthy, nondiabetic individuals appeared to have a tighter range of glucose, spending the vast majority of the 24-hour period between 71-120 mg/dl.

How Is Hypoglycemia Diagnosed
A medical diagnosis of hypoglycemia typically requires satisfying the Whipple triad. These three criteria include:
- Documented low glucose levels , often tested along with insulin levels and sometimes with C-peptide levels)
- Symptoms of hypoglycemia when the blood glucose level is abnormally low
- Reversal of the symptoms when blood glucose levels are returned to normal
Primary hypoglycemia is rare and often diagnosed in infancy. People may have symptoms of hypoglycemia without really having low blood sugar. In such cases, dietary changes such as eating frequent small meals and several snacks a day and choosing complex carbohydrates over simple sugars may be enough to ease symptoms.
Testing Times For Type 1 Diabetes
People with type 1 diabetes generally test their blood-sugar levels between four and ten times daily, including:
- Before all meals
- Before or during exercise or periods of physical exertion
- Before going to bed
- Sometimes at night.
You may need to test more often when youre ill, starting a new medication, or undergoing a major change in routine.

What Are Blood Sugar Levels
Your blood sugar levels, also known as blood glucose levels, are a measurement that show how much glucose you have in your blood. Glucose is a sugar that you get from food and drink. Your blood sugar levels go up and down throughout the day and for people living with diabetes these changes are larger and happen more often than in people who donât have diabetes.

Blood Sugar Levels 2 Hours After Youve Eaten
Many foods have types of carbohydrates called starches and sugars. When you eat foods with these types of carbohydrates, your body breaks them down into glucose, which is a type of simple sugar, and releases the glucose into your bloodstream. Aside from glucose produced by your liver, food is the main source of plasma glucose.
Two hours after eating, your blood sugar levels rise. They rise more when you eat more carbohydrates, when you do not eat fiber, fat, or protein with your carbs, and when you eat certain types of carbohydrates, such as refined sugars and starches.
These are target values from The Joslin Diabetes Center, which include levels for people with diabetes:

Why Test 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.

Blood Sugar Level Charts For Those With Diabetes
Normal blood sugar levels, for those with diabetes, will vary depending on someones age and the time of day. For example, when fasting, blood sugar levels are often in the target goal range. The type of food eaten will impact blood sugar levels in different ways. A meal with a lot of carbohydrates will raise blood sugar quicker than a meal that contains carbohydrates, protein, and fat . Blood sugar will rise after a meal, but will start to return to normal levels in several hours.
Lets take a look at what blood sugar levels should be, in those with diabetes, based on their age.
Low Blood Sugar Symptoms

Low blood sugar, also called hypoglycemia, is what happens when blood glucose levels drop too low. People who take insulin may have low blood sugar if they take too much insulin or mistime the insulin dose in relation to food, or if they exercise more than usual when there is fast-acting insulin on board .
Your healthcare provider will tell you when and how to check blood sugar, and when and how to treat low blood sugar. A low blood sugar is generally considered to be less than 70 mg/dL. A dangerously low blood sugar is below 54 mg/dL.
Low blood sugar can also be caused by many things including certain medications or combinations of medications, alcohol, endocrine disorders, eating disorders, and disorders of the liver, kidneys, or heart.
Here are some of the most common symptoms that someone with low blood sugar might experience:
- Lightheadedness
If your blood sugar is low you might start to feel some of the first signs of hypoglycemia like dizziness, lightheadedness, or sweating. The only way to know for sure if your blood sugar is low is to test it with a glucose meter or monitor it with a continuous glucose monitor such as the Dexcom G6.
If your blood sugar is low , a general rule of thumb is to consume 15 grams of fast-acting carbs to raise your blood sugar levels and avoid further symptoms, according to the American Diabetes Association . Your healthcare provider will give you a plan for what to do in case of low blood sugar that is specifically designed for you.

Hba1c Test For Diabetes Diagnosis
An HbA1c test does not directly measure the level of blood glucose, however, the result of the test is influenced by how high or low your blood glucose levels have tended to be over a period of 2 to 3 months.
Indications of diabetes or prediabetes are given under the following conditions:
- Normal: Below 42 mmol/mol
- Prediabetes: 42 to 47 mmol/mol
- Diabetes: 48 mmol/mol
There are two types of blood sugar levels that may be measured. The first is the blood glucose level we get from doing finger prick blood glucose tests. These give us a reading of how high our levels are at that very point in time.
The second is the HbA1c reading, which gives a good idea of our average control over a period of 2 to 3 months. The target blood glucose levels vary a little bit depending on your type of diabetes and between adults and children.
Where possible, try to achieve levels of between 4 and 7 mmol/L before meals and under 8.5 mmol/L after meals. The target level for HbA1c is under 48 mmol/mol .
Research has shown that high blood glucose levels over time can lead to organ and circulation damage.
Keeping blood glucose above 4 mmol/l for people on insulin or certain medications for type 2 diabetes is important to prevent hypos occurring, which can be dangerous.
Your doctor may give you different targets. Children, older people and those at particular risk of hypoglycemia may be given wider targets.

What Is A Fasting Blood Sugar Test
A fasting blood glucose test, also known as a fasting plasma glucose test or fasting blood sugar test, is a method for measuring the amount of glucose in the blood after a period of fasting. Most commonly, fasting occurs overnight and the test is performed first thing in the morning.
There are two primary purposes of a fasting blood glucose test:
- To diagnose diabetes
- To understand how different factors affect your blood sugar throughout the day
A fasting blood glucose measurement can be taken by a healthcare professional by blood draw and sent to a lab, or as a fingerstick test performed at home. The two processes are testing the same thing, so they are often referred to in the same way. A healthcare professional may order a lab test to eliminate other variables that may come into play with a fingerstick test, such as substances on the hand or not using a large enough blood drop.
If your healthcare team suspects that you may have prediabetes or type 2 diabetes, they may perform a fasting plasma glucose test or an A1C test. If you have already been diagnosed with diabetes, checking your fasting blood sugar level in the morning gives you a baseline blood sugar reading for your day. These tests can be performed at home as recommended by your healthcare team, using a blood glucose meter. However, the at-home blood glucose meter testing method is not intended for the diagnosis of diabetes.

Normal Hba1c For Person Without Diabetes
For someone who does not have diabetes, a normal HbA1C level is below 5.7%. An A1C between 5.7% to 6.4% is indicative of prediabetes.
Its recommended that adults over the age of 45 or adults under 45 who are overweight and have one or more risk factors for diabetes have a baseline A1C checked. If the result is normal, the A1C should be checked every three years. If the result indicates prediabetes, the A1C should be checked every one to two years.

Why The Test Is Performed
Your doctor may order this test if you have signs of diabetes . More than likely, the doctor will order a fasting blood sugar test.
The blood glucose test is also used to monitor people who already have diabetes.
The test may also be done if you have:
- An increase in how often you need to urinate
- Recently gained a lot of weight
SCREENING FOR DIABETES
This test may also be used to screen a person for diabetes.
High blood sugar and diabetes may not cause symptoms in the early stages. A fasting blood sugar test is almost always done to screen for diabetes.
If you are over age 45, you should be tested every 3 years.
If you’re overweight and have any of the risk factors below, ask your health care provider about getting tested at an earlier age and more often:
- High blood sugar level on a previous test
- Blood pressure of 140/90 mm Hg or higher, or unhealthy cholesterol levels
- History of heart disease
- Member of a high-risk ethnic group
- Woman who has been diagnosed with gestational diabetes
- Polycystic ovary disease
- Close relative with diabetes
- Not physically active
Children age 10 and older who are overweight and have at least two of the risk factors listed above should be tested for type 2 diabetes every 3 years, even if they have no symptoms.
How To Do A Finger
Your healthcare team will show you how to do it the first time, but these are the key steps:
- Wash your hands with soap and warm water. Dont use wet wipes as the glycerine in them can affect the test result. Make sure your hands are warm so its easier to get blood and wont hurt as much.
- Take a test strip and slot it into the meter to turn it on. Some meters will have tests strips built in.
- Remove the cap from your finger prick device and put in a new lancet. Then put the cap back on and set the device by pulling or clicking the plunger.
- Choose which finger to prick but avoid your thumb or index finger . And dont prick the middle, or too close to a nail. Place the device against the side of your finger and press the plunger. Use a different finger each time and a different area.
- Take your meter with the test strip and hold it against the drop of blood. Itll tell you if the test strip is filled, usually by beeping.
- Before you look at your reading, check your finger. Use a tissue to stop bleeding, then use it to take out the lancet and throw it away in your sharps bin.
- You can use the same tissue to take out the test strip and throw that away too. Taking out the strip will usually turn the meter off.
