The Big Picture: Checking Your Blood Sugar

How to test your blood glucose (sugar) levels

Blood sugar monitoring is the primary tool you have to find out if your blood glucose levels are within your target range. This tells you your blood glucose level at any one time.

Its important for blood sugar levels to stay in a healthy range. If glucose levels get too low, we can lose the ability to think and function normally. If they get too high and stay high, it can cause damage or complications to the body over the course of many years.

The logging of your results is vital. When you bring your log to your healthcare provider, youll have a good picture of your body’s response to your diabetes care plan. To help keep track of your levels, we have a glucose log. We also have a blood glucose log available for purchase that is smaller so you can carry it with you.

What Are Clinical Trials For Low Blood Glucose

Clinical trialsand other types of clinical studiesare part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.


Researchers are studying many aspects of low blood glucose levels in diabetes, such as

  • how to diagnose and treat low blood glucose among people with diabetes
  • medicines that can treat symptoms of low blood glucose in people with hypoglycemia unawareness
  • educational approaches to reduce fear of low blood glucose, which can make it harder for you to control your diabetes

What Are The Target Ranges

Blood glucose targets are individualized based on:

  • duration of diabetes
  • conditions a person may have
  • cardiovascular disease or diabetes complications
  • hypoglycemia unawareness
  • individual patient considerations

The American Diabetes Association suggests the following targets for most nonpregnant adults with diabetes. A1C targets differ based on age and health. Also, more or less stringent glycemic goals may be appropriate for each individual.

  • A1C: Less than 7%A1C may also be reported as eAG: Less than 154 mg/dL
  • Before a meal : 80130 mg/dL
  • 1-2 hours after beginning of the meal *: Less than 180 mg/dL

How Frequently Should I Measure My Blood Sugar

The Centre for Health Protection in Hong Kong advises you to measure your 2-4 times per week at various times during the day . You should monitor your blood sugar more often if:


  • Your blood glucose often tested too high or too low
  • If you are pregnant or preparing for pregnancy
  • During illness
  • If there are changes in your daily routine, such as a trip abroad, an unusual level of physical exercise, or changes in diet.
  • How To Use A Blood Sugar Meter

    There are different kinds of meters, but most of them work the same way. Ask your health care team to show you the benefits of each. In addition to you, have someone else learn how to use your meter in case youre sick and cant check your blood sugar yourself.

    Below are tips for how to use a blood sugar meter.

  • Make sure the meter is clean and ready to use.
  • After removing a test strip, immediately close the test strip container tightly. Test strips can be damaged if they are exposed to moisture.
  • Wash your hands with soap and warm water. Dry well. Massage your hand to get blood into your finger. Dont use alcohol because it dries the skin too much.
  • Use a lancet to prick your finger. Squeezing from the base of the finger, gently place a small amount of blood onto the test strip. Place the strip in the meter.
  • After a few seconds, the reading will appear. Track and record your results. Add notes about anything that might have made the reading out of your target range, such as food, activity, etc.
  • Properly dispose the lancet and strip in a trash container.
  • Do not share blood sugar monitoring equipment, such as lancets, with anyone, even other family members. For more safety information, please see Infection Prevention during Blood Glucose Monitoring and Insulin Administration.
  • Store test strips in the container provided. Do not expose them to moisture, extreme heat, or cold temperatures.

    What Do My Results Mean

    When you finish the blood sugar check, write down your results and note what factors may have affected them, such as food, activity, and stress. Take a close look at your blood glucose record to see if your level is too high or too low several days in a row at about the same time. If the same thing keeps happening, it might be time to change your diabetes care plan. Work with your doctor or diabetes educator to learn what your results mean for you. It can take time to make adjustments and get things just right. And do ask your doctor if you should report results out of a certain range right away by phone.

    Keep in mind that blood glucose results often trigger strong feelings. Blood sugar numbers can leave you upset, confused, frustrated, angry, or down. It’s easy to use the numbers to judge yourself. Remind yourself that tracking your blood sugar level is simply a way to know how well your diabetes care plan is working, and whether that plan may need to change.


    What Should My Blood Sugar Levels Be

    How To Test Blood Sugar Levels

    Your blood sugar level changes depending on what you’ve eaten, whether you’ve exercised and other factors but we have some general guidelines to determine what levels are healthy.

    For generally healthy individuals who haven’t eaten for eight hours or more, a normal blood sugar level is between 70-99 mg/dL. When you’ve eaten in the past two hours, it should be no higher than 140 mg/dL. To refresh your chemistry knowledge, that unit is milligrams per deciliter and it’s measuring the amount of glucose present in your blood.

    Only a medical professional can diagnose diabetes or another issue with your blood sugar, so if you’re concerned about your blood sugar levels, check with a doctor.

    All You Need To Know About Reading Your Blood Glucose Test Report

    Written by Dr Anitha Anchan | Updated : April 26, 2016 5:29 PM IST

    Glucose is a type of sugar that is produced by the digestion of dietary carbohydrates. It is transported by the blood to all parts of the body and is body s main source of energy. Insulin, a hormone produced by the pancreas, transfers extra glucose from the blood to muscle, fat, and liver cells where it is stored. Blood glucose levels changes indicate abnormal digestion process. People with diabetes often have high levels of glucose in their blood.

    Prediabetes is a condition where the blood glucose is higher than normal but not high enough to be confirmed as diabetes. It could lead to diabetes if appropriate measures are not taken.

    Oral Glucose Tolerance Test

    This test is not now usually used to diagnose diabetes. However, the test may be done if it is thought your body doesn’t control glucose levels normally but not badly enough to be called diabetes. This is referred to as pre-diabetes . The test may also be used to see whether a woman has developed diabetes associated with pregnancy.

    For this test, you fast overnight. In the morning you are given a drink which contains 75 g of glucose. A blood sample is taken two hours later. Normally, your body should be able to deal with the glucose and your blood level should not go too high. A glucose level of 11.1 mmol/L or more in the blood sample taken after two hours indicates that you have diabetes. See the separate leaflet called Glucose Tolerance Test for more details.

    Blood glucose testing is easier, less painful, and more accurate than ever. Blood sugar levels can be tested with a blood glucose meter, a computerized device that measures and displays the amount of glucose in a blood sample.

    To get a blood sample, a small needle called a lancet is used to prick the skin to draw a drop of blood. The drop of blood is placed on a testing strip that goes into the glucose meter, and the blood glucose reading appears on a screen within a few seconds.

    Many types of glucose meters are available with different features. But most people choose the type of equipment covered by their insurance plans.

    Blood Sugar Instability Symptoms

    Insulin resistance does not happen all-of-a-sudden. Rather it builds over time and increasingly contributes to health problems. Understanding the signs of poor blood sugar control is the best way to be proactive in this regard. There are several telling signs that your body is not stabilizing blood sugar effectively.


    Some of the most common include:

    • Cravings
    • Unstable Energy Levels
    • Sudden Intense Hunger

    Most commonly, these symptoms arise simply because someone is consuming too many carbohydrates and sugar throughout the day. This is why I always start with a Keto Metabolic Makeover to kick start a fat-burning state and help people step off the blood sugar rollercoaster. If you are commonly experiencing these symptoms, it is imperative to test blood sugar levels periodically as these symptoms can be effectively controlled by doing so.

    The Best Healthcare Options To Prevent Diabetes

    Health care is expensive. Canada spent an estimated $253.5 billion in 2018, and as the cost of health care increases, so does the cost to you. Pre-existing medical conditions, family history, and BMI are all factors that increase the cost of health care. These factors also increase your risk of diabetes, so you must be covered.

    Of course, as a Canadian, you are entitled to some free and subsidized health care, which is great. But many people opt for private healthcare and for diabetes prevention this can be very useful. If you’re shopping around for private healthcare, it’s important to choose the right package.

    Basic health insurance will usually cover health care, medical services, and prescriptions, but they tend to lack customizations. If you opt for a premium/guaranteed health insurance you have the bonus of a custom plan based on your needs if you are worried about your risk of diabetes this is like gold dust.


    Private healthcare plans can cover the cost of many expenses related to diabetes such as blood tests, blood sugar monitors, specialist referrals, hospital stays, and much more! The most important thing to note about private health care is that it covers costs for preventative care, not just treatment for diseases.

    There are many different options available, so make sure you search for the best quotes.
