Common Mistakes to Avoid When Using a Blood Glucose Meter
Related reading: Blood Sugar Basics What Every Person Should Know
Managing blood sugar levels is critical for individuals with diabetes. A key tool in this management is the blood glucose meter. However, improper usage can lead to inaccurate readings, affecting treatment decisions and potentially jeopardizing health. This article highlights common mistakes to avoid when using a blood glucose meter, ensuring you get reliable results for effective diabetes management.
Understanding Your Blood Glucose Meter
Before delving into the mistakes, it's important to understand what a blood glucose meter is and its purpose. A blood glucose meter measures the amount of glucose (sugar) in your blood at a specific point in time. It requires a small blood sample, typically obtained by pricking your fingertip. Accurate readings from a blood glucose meter help you make informed decisions about your diet, exercise, and medication.
Common Mistakes and How to Avoid Them
Here's a breakdown of the common mistakes people make when using a blood glucose meter, along with practical tips on how to avoid them:

1. Incorrect Coding or Calibration
One of the most frequent errors is using the wrong code or neglecting to calibrate your blood glucose meter. Many meters require you to enter a code that matches the batch number on your test strips. Failing to do so, or using expired test strips, can lead to significantly inaccurate readings.
- Solution: Always verify the code on your meter matches the test strip batch number. Some newer meters automatically code, but it’s always wise to double-check. Replace expired test strips, as their chemicals degrade over time.
2. Improper Hand Hygiene
Contaminants on your hands can interfere with the accuracy of your blood glucose meter readings. Food residue, lotions, or even sweat can skew the results, leading to unnecessary concern or incorrect treatment.
- Solution: Wash your hands thoroughly with soap and warm water before testing. Dry them completely with a clean towel. If you are in a situation where soap and water aren't available, use an alcohol-based hand sanitizer, but ensure it's completely dry before proceeding.
3. Insufficient Blood Sample
If the blood sample applied to the test strip is too small, the blood glucose meter may display an error message or produce an inaccurate result. Skimping on the sample size to avoid another finger prick is tempting, but it's not worth the inaccurate reading.
- Solution: Ensure you obtain an adequate blood sample by using the correct lancing device settings. Apply gentle pressure around the puncture site, but avoid squeezing too hard, which can dilute the sample with tissue fluid. Follow the specific instructions for your meter to ensure the right amount of blood is used.
4. Improper Storage of Test Strips
Test strips are sensitive to environmental factors such as temperature and humidity. Storing them in areas where they are exposed to these elements can compromise their effectiveness, resulting in unreliable readings from your blood glucose meter.
- Solution: Always store your test strips in their original container, tightly sealed, in a cool, dry place. Avoid storing them in the bathroom or near sources of heat or moisture. Check the expiration date regularly and discard expired strips.
5. Using Expired Test Strips
Similar to the improper storage of test strips, using expired test strips leads to inaccurate results. The chemicals in test strips degrade over time, making them less effective.
- Solution: Always check the expiration date on the test strip vial before using them. Discard expired test strips promptly. Even if the strips appear fine, their chemical composition has likely altered, affecting reading accuracy.
6. Incorrect Lancing Technique
The way you lance your finger can also affect the accuracy and pain level of your blood glucose test. Insufficient depth or improper location can make it difficult to obtain a sufficient blood sample and cause unnecessary discomfort.

- Solution: Use the correct lancing device settings to ensure adequate depth. Rotate your puncture sites to avoid developing calluses or soreness. The sides of your fingertips are generally less sensitive than the center.
7. Ignoring Meter Maintenance
Blood glucose meters require periodic maintenance to ensure they are functioning correctly. Neglecting to clean or calibrate your meter as recommended can lead to inaccurate readings.
- Solution: Clean your blood glucose meter regularly according to the manufacturer's instructions. Consider control solution testing periodically to ensure your meter is calibrated properly. If you suspect your meter is malfunctioning, contact the manufacturer for assistance.
8. Not Following Manufacturer Instructions
Every blood glucose meter is different, and it's vital to follow the manufacturer's instructions carefully. Skipping instructions can lead to improper use, resulting in inaccurate readings and affecting your diabetes management.
- Solution: Read the instruction manual thoroughly before using your blood glucose meter. Pay attention to the specific recommendations for your meter model, as they can vary significantly.
The Importance of Accurate Blood Glucose Monitoring
Accurate blood glucose monitoring is crucial for effective diabetes management. It enables you to make informed decisions about your diet, exercise, and medication, helping you maintain healthy blood sugar levels and prevent complications. By avoiding these common mistakes and following the recommended guidelines, you can ensure that your blood glucose meter provides reliable results, supporting your journey to better health.

Even when you’re careful, issues can still arise with your blood glucose meter. Here’s a basic troubleshooting guide:
Issue | Possible Cause | Solution |
---|---|---|
Error Message | Insufficient blood sample, expired test strip, or meter malfunction. | Retest with a fresh strip and adequate blood. If problem persists, contact manufacturer. |
Readings Seem Inaccurate | Improper coding, contaminated hands, or faulty meter. | Verify coding, wash hands thoroughly, and consider control solution testing. |
Meter Won't Turn On | Dead battery or damaged device. | Replace the battery or contact the manufacturer for repair or replacement. |
Conclusion
Using a blood glucose meter correctly is a skill that improves with practice. By being mindful of these common mistakes and taking the necessary precautions, you can ensure you get the most accurate and reliable readings possible, ultimately contributing to better diabetes management and improved quality of life. Always consult with your healthcare provider for personalized advice and guidance regarding your diabetes care.
