- Why it Matters: Expired or damaged test strips lose their accuracy, providing misleading information about your blood glucose levels.
Example Table of Storage Conditions:
| Condition | Recommendation | Potential Impact of Ignoring | | -------------- | -------------------------------------- | --------------------------- | | Temperature | Store between 36°F and 86°F (2°C and 30°C) | Inaccurate readings | | Humidity | Keep in a dry environment | Degradation of chemicals | | Sunlight | Avoid direct sunlight | Accelerated expiration | | Vial Closure | Keep tightly closed | Moisture contamination | What To Eat To Treat Hypoglycemia Safely And Quickly
3. Incorrect Blood Sample Size
Another common error involves applying an insufficient amount of blood to the test strip. Most blood glucose meters require a specific sample size to function correctly. If you don't provide enough blood, the meter may display an error message or, worse, provide a false reading.
- The Mistake: Not applying a sufficient blood sample to the test strip.
- The Solution: Ensure you obtain an adequate blood sample. Follow the manufacturer's instructions for your specific meter. Many meters have a fill window or indicator to help you apply the correct amount of blood. If the first attempt is unsuccessful, use a new test strip and try again. Avoid squeezing the finger excessively, as this can dilute the blood sample with tissue fluid, leading to inaccurate readings.
- Why it Matters: An insufficient blood sample can lead to falsely low or high readings, compromising the accuracy of your blood glucose monitoring.
4. Improper Lancing Technique
The technique used to obtain a blood sample can also impact accuracy. Factors like the lancing site, depth setting, and cleanliness of the lancing device all play a role.
- The Mistake: Using the same lancing site repeatedly, setting the lancing device to an insufficient depth, or not cleaning the lancing device regularly.
- The Solution:
- Rotate Lancing Sites: Rotate your lancing sites to avoid soreness and calluses. Using the sides of your fingertips is often less painful than the center.
- Adjust Lancing Depth: Adjust the depth setting on your lancing device to obtain a sufficient blood sample without excessive squeezing. Start with a lower setting and increase it gradually until you get the required blood volume.
- Clean Lancing Device: Clean your lancing device regularly according to the manufacturer's instructions. Replace the lancet after each use to prevent infection and ensure optimal performance.
- Why it Matters: Proper lancing technique minimizes pain, ensures adequate blood flow, and prevents infection, all of which contribute to accurate blood glucose readings.
5. Meter Calibration and Coding Issues
Some blood glucose meters require calibration or coding to match the specific batch of test strips being used. Failing to calibrate or code the meter correctly can result in significant inaccuracies. Achieving Long Term Diabetes Management A Step By Step Plan
- The Mistake: Forgetting to calibrate the meter or entering the incorrect code for the test strips.
- The Solution:
- Follow Instructions: Carefully read and follow the manufacturer's instructions for calibrating or coding your meter.
- Check Codes: Check the code on the test strip vial and ensure it matches the code entered into the meter. Some meters automatically detect the code, while others require manual entry.
- Control Solution Testing: Periodically perform control solution testing to verify the accuracy of your meter and test strips. Control solutions contain a known amount of glucose and can help identify potential issues.
- Why it Matters: Proper calibration and coding ensure that your meter is accurately interpreting the results from the test strips.
6. Ignoring Meter Error Messages and Control Solutions
Blood glucose meters are designed to display error messages when they detect a problem, such as an insufficient blood sample or a malfunctioning test strip. Ignoring these messages can lead to inaccurate readings and compromised diabetes management. Control solutions are a crucial tool for ensuring the accuracy of your meter and test strips.
- The Mistake: Disregarding error messages or not using control solutions regularly.
- The Solution:
- Understand Error Messages: Familiarize yourself with the error messages your meter displays and what they mean. Refer to the user manual for troubleshooting instructions.
- Use Control Solutions: Use control solutions regularly, especially when you open a new vial of test strips, suspect the meter is malfunctioning, or your blood glucose readings seem inconsistent.
- Record Results: Keep a record of your control solution test results to track the performance of your meter and test strips over time.
- Why it Matters: Error messages and control solutions provide valuable feedback about the performance of your monitoring system, allowing you to identify and correct potential issues.
