What Is Self Monitoring of Blood Glucose SMBG? Self monitoring of blood glucose or SMBG refers to home blood glucose testing for people with diabetes.
Self monitoring is the use of regular blood testing to understand one’s diabetes control and inform changes to improve one’s control or wider regime.
Self monitoring of blood glucose levels has been a hotly disputed issue for a number of years, particularly with regards to people with type 2 diabetes who are not on insulin.
For information and advice on what to do if your access to testing supplies is restricted, see our availability of test strips page.
Willingness and committment
The benefits tend to be most pronounced when the patient displays a willingness and commitment to test and has been given enough education on when to test blood glucose levels and interpreting the results to get the most out of the testing.
Benefits of self monitoring of blood glucose
There are a number of benefits of home blood glucose testing:
- Helps to determine which foods or diet are best for one’s control
- Helps inform the patient and doctor about how well the medication regime is working
- Reduces anxiety about, and increases understanding of, hypoglycemia
- Its important for undertaking dangerous tasks which could be influenced by high or low blood sugar, such as driving and handling dangerous machinery
The benefits are most pronounced when there is willingness and commitment to test on the patients’ part and they have been given enough information and training on when to test blood glucose levels and interpreting the results to get the most out of the testing.
Every diabetic is different, so it is best to ask your doctor when and how often you should check your blood sugars. If you’re sick, you may need to test more often. Monitoring blood sugar at home can help determine your blood sugar level to see if you need to adjust your diet, exercise, or any medications. Low blood sugar levels or hypoglycaemia can lead to seizures or a coma if left untreated whereas high blood sugar or hyperglycaemia can cause ketoacidosis, which again is a life-threatening condition. Hyperglycemia over a long period can increase the risk for neuropathy (nerve damage), along with heart, kidney, and eye diseases in diabetics. Also, home testing becomes even more crucial if you have type 2 diabetes and have a diet- and exercise-based treatment plan.
What you learn from testing your blood sugar levels?
According to the American Diabetes Association (ADA), the following are the target blood sugar levels:
– Between 80 and 130 mg/dL before meals
– Less than 180 mg/dL two hours after meals
Your doctor can help set your blood sugar goals as these values may vary with age, severity of diabetes, presence of any complications and overall health and other medical conditions. Some experts recommend testing blood sugar levels three times a day. The time of the day at which you test your blood sugar level reveals some important information. If you do a test in the mornings before eating you will be able to understand how well your body is regulating blood sugars overnight. Testing blood sugars before or one or two hours after the beginning of your meal helps you understand how food and portion choices affect the values as well as how well your treatment pan is working to control the increase in blood sugar level from the last meal. Similarly, if you test before a meal, it will tell whether or not your bloods sugar level has returned to target since your last meal and if you need to adjust the carbohydrates in your next meal. A test before any physical activity like a workout is important to know if you need a snack before you start the activity and testing after the activity will reveal the effect of the activity on the sugar levels. You should also test when you’re sick as stress elves have a direct impact on blood sugar levels.
Buying And Using A Glucometer?
The first step is to meet your doctor to discuss when and how frequently you should test and what your target values should be. It is then important to buy a reliable and accurate glucometer for blood sugar testing as this is the most imprint tool in SMBG. Whether you’re looking for blood glucose meters, test strips, or apps, OneTouch has what you need to help you manage your diabetes. Using ISO-15197:2013 certified glucometers ensure your accurate blood glucose level. Simple to use glucometers with colour coding technology such as ColorSure Technology of OneTouch glucometers help patients to understand the correct meaning of the blood glucose value. Patients can take immediate actions based on the low and high blood glucose values indicated by ColorSure Technology.

2. OneTouch Verio Flex System:
OneTouch Verio Flex blood glucose monitoring system, with ColorSure™ technology – is a simple, accurate and easy-to-use meter that takes the guesswork out of understanding blood sugar test results for people with diabetes. Its simple colour range indicator uses colour to instantly tell patients when their blood glucose readings are “low,” “in range,” or “high” so they can quickly get on with their lives.
This blood sugar monitoring device is certified to the latest international standards for accuracy (EN ISO 15197:2015 ) and offers virtually a pain free testing with the OneTouch Delica Plus lancing device. OneTouch Verio Flex™ blood glucose monitoring system syncs data seamlessly with the free OneTouch Reveal mobile app. The OneTouch Reveal app with ColorSure technology automatically organizes your blood sugar results in a color-coded logbook and dashboards that link with your logged food, insulin and activity. It also helps you See and share your progress with your family, friends or trusted care network.
You can then learn how to measure your blood glucose properly by following these steps:
Wash your hands with soapy water and dry them well.
Insert the test strip into the glucometer.
Prick the end of a finger (on the side). You can gently squeeze the end of your finger, if necessary.
Apply the blood to the test strip.
Wait a few seconds or the time indicated on the glucomter.
Read and write down the result in a logbook or store it in the glucose meter.
Disadvantages of home blood glucose testing
The disadvantages are mainly seen when either the patient lacks motivation to test or does not have sufficient education on how to interpret the results to make sufficient use of home testing equipment.
Where this is the case, the following disadvantages may outweigh the potential benefits:
- Anxiety about one’s blood sugar control and state of health
- The physical pain of finger pricking
- Expense to the NHS
What are the ADA guidelines for self monitoring of blood glucose SMBG frequency?
However, the frequency and timing of SMBG are not without controversy. The American Diabetes Association (ADA) states that those on multiple daily injections or on an insulin pump should self-test 3-4 times a day. One good rule of thumb is to always test before an insulin injection or a bolus.
What is the difference between CGM and SMBG?
SMBG provides only snap-shots of blood glucose concentration, and is limited by the number of finger-sticks a patient is willing to perform per day. In contrast, CGM can report up to 288 glucose values per day and yield data revealing temporal trends and patterns in glucose control (16).
Continuous Glucose Monitoring Versus Self-monitoring of Blood Glucose in Children with Type 1 Diabetes- Are there Pros and Cons for Both?
Glucose monitoring is essential for modern diabetes treatment and the achievement of near-normal glycemic control. Monitoring provides the data necessary for patients to make daily management decisions related to food intake, insulin dose, and physical exercise and can enable patients to avoid potentially dangerous episodes of hypo- and hyperglycemia. Additionally, monitoring can provide health care providers with the information needed to identify glycemic patterns, educate patients, and adjust insulin.
Presently, youth with type 1 diabetes can self-monitor blood glucose via home blood glucose meters or monitor glucose concentrations nearly continuously using a continuous glucose monitor. There are advantages and disadvantages to the use of either of these technologies. This review describes the two technologies and the research supporting their use in the management of youth with type 1 diabetes in order to weigh their relative costs and benefits.
