How to Properly Use a Blood Glucose Meter
Using a blood glucose meter correctly is crucial for obtaining accurate and reliable readings. There are several steps involved, each playing a key role in ensuring the validity of the test results. Before you begin, ensure you have all necessary equipment: a blood glucose meter, test strips compatible with your meter, a lancing device with fresh lancets, and alcohol swabs or another cleansing agent. Now, let’s delve into the process:
-
Wash Your Hands Thoroughly: Start by washing your hands with warm, soapy water. Dry them completely before you proceed. This step is essential to prevent contamination and inaccurate results. Ensure there’s no residual food or other substances on your fingers. If water and soap are not available, use an alcohol wipe to clean the chosen finger, let it air dry thoroughly, and only then proceed to the next steps.
-
Prepare the Lancing Device: Insert a new lancet into the lancing device according to the manufacturer’s instructions. Adjust the depth setting as necessary. The first few times using the device might require experimenting to determine the most comfortable and effective depth. Use a fresh lancet each time to ensure a sterile and virtually painless experience.
-
Insert the Test Strip: Take a test strip and insert it into the glucose meter. Most meters will automatically turn on. Ensure you're using the correct test strip for the meter you are using, and that the strip has not expired. An expired strip could lead to inaccurate results.
-
Choose a Finger for Testing: Select a fingertip for the blood sample, preferably on the side, as these areas are less sensitive. You can rotate between fingers from one testing to the next to avoid discomfort and soreness. Avoid using the thumb or index finger as these are often used for manual tasks.
-
Lance Your Finger: Press the lancing device firmly against the chosen spot, and press the trigger button. You might feel a brief sting, which subsides very quickly.
-
Apply Blood to the Test Strip: Gently squeeze the area of your finger near the puncture to create a small bead of blood. Touch the end of the test strip to the blood, allowing the strip to draw in the necessary sample. Be sure to follow manufacturer’s instructions for sample placement on the specific type of strip. If you don’t obtain a large enough blood sample, you may need to repeat steps 4-6. Ensure you do not ‘smear’ the blood across the strip, which could result in inaccurate test readings.
-
Wait for the Result: The meter will begin processing, and in a few seconds, display your blood sugar reading. Some meters also keep track of previous test results; which can be helpful to look at historical trends.
-
Record and Dispose: Once you see the result, record it in a logbook or an app, along with time, any meals taken, and any unusual activity/event which may have impacted your blood sugar reading. Dispose of the lancet and test strip safely as per guidelines of your community.
By following these steps consistently, you'll gain the most accurate and valuable insights from your blood glucose testing. Proper technique also minimizes potential errors, making it easier to maintain good health.
Common Mistakes to Avoid During Glucose Testing
Even when using a blood glucose meter regularly, it's easy to fall into common traps that compromise the accuracy of your results. Avoiding these errors can significantly enhance the value of your glucose readings and contribute to better diabetes management and overall health outcomes. Let’s break down some prevalent mistakes:
-
Reusing Lancets: A lancet is designed for single use. Reusing them dulls the needle tip and can cause more pain with each poke. Moreover, it raises the risk of infection as well as introducing potential contaminants. Using fresh lancets each time is very important.
-
Not Washing Hands: Food or other residues on your hands could distort the readings. Ensure you are washing thoroughly, or using an alcohol wipe each time before testing. In instances where alcohol wipes are used, allowing the area to air dry thoroughly is also very important.
-
Using Expired Strips: Using expired test strips can lead to inaccurate readings, which might be misleading and jeopardize your management of blood sugar levels. Always make sure to check the expiry date of the test strips before using.
-
Not Enough Blood Sample: If there's not enough blood, you may get an inaccurate reading. Also, forcing an additional sample onto an already filled strip, may also lead to a reading that is unreliable. Getting the sufficient sample in one attempt will ensure a correct reading.
-
Smearing the Blood on Test Strips: The blood sample needs to be drawn onto the test strip. Smearing or trying to manipulate the placement, could lead to a compromised sample resulting in an error or an unreliable reading. Always follow specific manufacturer guidelines.
-
Inconsistent Testing Times: Testing at random times can make it hard to compare data and identify patterns. Aim for regular, consistent times each day, as this is needed to develop trends and insights. Consistent test times in relation to meals and daily activities can allow for a deeper understanding of the impact of such events.
-
Inaccurate Meter Settings: Be aware of the meter's settings for date, time and type of results, and make adjustments as needed. Ensure your readings are recorded under the correct settings and units of measurement.
| Common Error | Impact on Accuracy | Solution |
|---|---|---|
| Reusing Lancets | Risk of infection; dull needle causes more pain; possibly contaminated testing | Use fresh lancet each time; dispose of used lancets correctly |
| Not Washing Hands | Contamination leading to skewed results | Always wash with soap and water before testing or use alcohol wipes correctly |
| Expired Strips | Test inaccuracies leading to incorrect diabetes management and potential complications | Check expiry dates; use only fresh, unexpired test strips |
| Insufficient Blood | Results can be erroneous or the testing could fail altogether | Gently squeeze fingertip; consider adjusting lancing depth; try again, if needed |
| Smearing Blood | Results can be skewed or rendered invalid | Let the test strip pull the blood itself; avoid smearing and manipulation |
| Inconsistent Testing | Difficult to identify patterns and changes in blood glucose | Establish a consistent routine; test at similar times each day |
| Incorrect Meter Settings | Result readings, records could be inaccurate | Ensure you set your meter with the correct date, time and units. |
Interpreting Blood Glucose Readings
Understanding what your blood glucose levels mean is just as vital as getting accurate readings. Knowing the target ranges and what they indicate can help you make informed choices about managing your diabetes or proactively taking steps to maintain good health. There are key levels you should be familiar with, keeping in mind that specific ranges can vary depending on your personal health status and treatment plan as set forth by your healthcare professional.
- Normal Ranges:
- Fasting Blood Sugar: For most healthy adults, a fasting blood glucose level (taken after at least eight hours of not eating) typically falls between 70 and 99 mg/dL (3.9 to 5.5 mmol/L).
- Postprandial Blood Sugar: Two hours after a meal, blood glucose levels are expected to be less than 140 mg/dL (7.8 mmol/L) for those without diabetes.
- Pre-Diabetes:
- Fasting: A level between 100 to 125 mg/dL (5.6 to 6.9 mmol/L) indicates impaired fasting glucose.
- Postprandial: A level between 140 to 199 mg/dL (7.8 to 11.0 mmol/L) 2 hours after a meal.
- Diabetes:
- Fasting: A reading of 126 mg/dL (7.0 mmol/L) or higher on two separate occasions often indicates diabetes.
- Postprandial: A reading of 200 mg/dL (11.1 mmol/L) or higher after 2 hours is indicative of diabetes.
What to Do if Your Readings Are Outside the Normal Ranges
-
High Readings (Hyperglycemia): Consistent readings that are higher than normal could signify several things, such as consuming high-sugar or high-carb foods, insufficient insulin dosage (in the case of diabetes), or underlying illness. If your blood sugar level is persistently high, it’s essential to speak with your health professional to address the root cause, especially to help adjust medication if required. Be aware of the symptoms of high blood sugar, such as frequent urination, increased thirst, and fatigue and seek professional help right away.
-
Low Readings (Hypoglycemia): Levels below 70 mg/dL (3.9 mmol/L) can indicate low blood sugar and may be a sign that you need to adjust your medications, or that you have not had enough to eat, or perhaps have just had too much exercise. Low blood sugar levels can cause symptoms like shakiness, dizziness, sweating and confusion. Consuming a source of simple sugar immediately, as well as speaking to a medical professional to determine next steps are of paramount importance.
Log Your Readings and Monitor Trends
Recording your readings, together with relevant information such as meals, time of test, physical activity, and general well-being is crucial for analysis of trends in readings over time. It could reveal significant impacts of certain foods or exercises on blood sugar levels, for example. Keeping a logbook also facilitates better communication between you and your healthcare professional, and ensures an improved, more effective management approach is in place.
By understanding how to interpret your blood sugar results, you will be able to take a more active, informed and responsible approach to overall health and wellness.
| Category | Fasting (mg/dL) | 2-Hour Postprandial (mg/dL) | Implication |
|---|---|---|---|
| Normal | 70-99 | Less than 140 | Healthy range |
| Pre-Diabetes | 100-125 | 140-199 | Risk of developing type 2 diabetes |
| Diabetes | 126 or higher | 200 or higher | Diabetes mellitus |
| Hypoglycemia | Below 70 | Not applicable | Indicates low blood glucose, requires action |
Lifestyle Factors that Impact Blood Glucose
Maintaining healthy blood glucose levels goes beyond just regularly checking them; lifestyle choices are pivotal in both achieving stable levels and avoiding potential health complications. Numerous factors can influence how your body manages glucose. Here's an overview of some critical lifestyle considerations:
Diet
Your diet directly affects your glucose levels, with certain foods causing bigger spikes than others. Focusing on a well-balanced diet that prioritizes whole grains, fruits, vegetables, lean proteins, and healthy fats is crucial to maintaining stable blood sugar levels. Try to eat smaller, frequent meals instead of larger infrequent ones to avoid drastic fluctuations, which can lead to spikes. Keep an eye on portion sizes to avoid consuming excess carbohydrates that tend to convert quickly into glucose.
- Carbohydrates: Choose complex carbohydrates like whole grains over simple sugars found in pastries and sugary drinks. Complex carbohydrates digest slower and will lead to more steady, stable levels of blood sugar.
- Fiber: Include adequate amounts of fiber, as fiber helps slow down glucose absorption. Great fiber sources are found in non-starchy vegetables, whole grains, and legumes.
- Portion Control: Practice portion control with each meal. Avoid over-consumption of foods that cause significant fluctuations in blood glucose levels.
- Hydration: Always drink plenty of water. Water helps with the overall metabolism and processing of blood glucose, as well as avoiding other complications arising from dehydration.
Physical Activity
Regular physical activity increases the sensitivity of cells to insulin, allowing them to use glucose more efficiently and thus improving your blood glucose readings. Exercise helps your body's metabolism and also helps control and manage stress. Always choose physical activities you enjoy and will likely stick to. Find something that fits your life and is easily integrated into a routine that works for you. Start slow and gradually increase as your endurance improves. Include both aerobic exercises (walking, swimming) and resistance training, which helps build lean muscle mass, thus aiding your glucose metabolism.
Stress
When under chronic stress, the body releases certain hormones that cause the liver to release stored glucose into the bloodstream, raising blood glucose levels. Practice regular relaxation techniques like meditation or deep breathing, which may help with the proper control of stress and its related consequences. Prioritize sleep to allow the body to reset itself, which will reduce the chances of elevated glucose levels caused by lack of sleep. Managing stress efficiently is not only good for glucose management, but also for overall well-being.
Sleep
Consistent, quality sleep is also essential in blood sugar management, as lack of it contributes to insulin resistance, elevated glucose levels, and general reduction in physical and emotional wellness. Try to maintain regular sleep hours, at least seven hours, to ensure that the body is in proper balance and has the required recovery time it needs. Avoid stimulating activities before bed that will disrupt good sleep. Set up an environment that is conducive to rest, which is needed for health and proper management of overall body processes, including those related to glucose regulation.
Other Factors
Other factors that may also have an impact are medication, alcohol and caffeine use, smoking, and dehydration. Being mindful of these factors and knowing their effect can help with overall blood glucose management and will make positive improvements to one's overall health and well-being.
| Lifestyle Factor | Impact on Blood Glucose | Recommended Strategies |
|---|---|---|
| Diet | Directly affects postprandial levels | Balanced diet, whole grains, fiber-rich foods, portion control |
| Exercise | Increases insulin sensitivity, lowers levels | Regular physical activity, a mix of aerobic and strength training |
| Stress | Stress causes increase in cortisol release, leads to elevated levels | Relaxation techniques, mindfulness, time management, adequate rest |
| Sleep | Poor sleep leads to insulin resistance | Consistent sleep schedule, adequate hours of rest; 7-9 hours |
When to Seek Professional Guidance for Blood Glucose Monitoring
While blood glucose monitoring is a self-management tool, there are instances when it’s critical to consult with a healthcare professional. Knowing when to seek guidance ensures your health is being managed effectively and any potential problems are addressed promptly.

Ongoing hyperglycemia, or persistently high blood sugar can result in severe, long-term complications that could lead to heart disease, kidney disease, vision damage, and nerve issues, and should therefore be addressed promptly. Seek professional advice to modify a treatment plan, and adjust medications or other therapies that can keep blood glucose levels under better control. It’s important that healthcare professionals evaluate all relevant factors and ensure a proper treatment plan, specific to the particular circumstances of an individual.
Frequent Low Readings
Repeated occurrences of hypoglycemia, which is low blood sugar, also need immediate medical advice. Very low levels could lead to seizures, confusion, or even loss of consciousness, and should be addressed right away. Frequent hypoglycemia may be the result of excessive amounts of medication, excessive physical activity, an inadequate food intake, or some other health-related condition, all of which will need to be thoroughly evaluated by your healthcare professional. Proper analysis will help to determine the specific cause and the steps to be taken to avoid future low glucose events.
Changes in Medication
Never change, adjust, or stop medications without first consulting your physician or a healthcare professional. Medication management needs to be customized based on specific and individualized health considerations, as well as related external factors that may impact your body at a given time. Self-adjusting medications can be risky and lead to adverse results or long-term complications. Follow all medical advice carefully, and ensure to ask clarifying questions when things are not clear.
Significant Lifestyle Adjustments
Making substantial adjustments to your diet, or physical activity can affect blood glucose levels, which should therefore be under the guidance of a medical professional. Changes need to be done in consultation with a healthcare professional, especially when the blood glucose readings are unstable. In cases where large amounts of exercise are done on a regular basis, medication levels or meals may need to be adjusted.
During Illness
When sick, blood glucose levels can fluctuate widely. It is during these periods of illness, particularly when there is vomiting or dehydration, that it becomes important to keep an extra close watch on blood sugar levels, and to seek immediate professional help when fluctuations do not seem manageable. The body may be more stressed under an illness, which would make it less predictable with regards to blood sugar level control. Seek medical guidance to adapt your self-management routine under illness or adverse health conditions.
