Diabetic test strips are a cornerstone of effective diabetes management, providing crucial information about your blood glucose levels. However, their accuracy can be compromised by common mistakes during use. Understanding these errors and learning how to avoid them can help ensure that your test results are reliable and that you manage your diabetes more effectively. In this blog, we’ll highlight frequent mistakes people make with test strips and offer practical advice on how to avoid them.
1. Using Expired Test Strips
Mistake: Using test strips past their expiration date can lead to inaccurate readings. Expired strips may not react properly with your blood sample, leading to erroneous results.
How to Avoid It:
- Check Expiration Dates: Regularly check the expiration dates on your test strip containers. Dispose of any expired strips and replace them with new ones.
- Track Opened Containers: Keep track of when you open a new container of test strips. Follow the manufacturer’s guidelines for how long the strips are effective after opening.
2. Incorrect Storage Conditions
Mistake: Improper storage of test strips, such as exposure to heat, moisture, or sunlight, can degrade the strips and affect their accuracy.
How to Avoid It:
- Store Properly: Keep test strips in their original container with the lid tightly closed. Store them in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Humid Areas: Do not store test strips in high-humidity environments like bathrooms. Moisture can affect the strips’ performance.
3. Not Following the Meter’s Instructions
Mistake: Each glucose meter has specific instructions for inserting test strips and obtaining blood samples. Not following these instructions can lead to incorrect readings.
How to Avoid It:
- Read the Manual: Familiarize yourself with your meter’s user manual and follow the manufacturer’s instructions precisely.
- Consult Support: If you’re unsure about any steps, consult the manufacturer’s customer support or ask your healthcare provider for assistance.
4. Touching the Test Strip with Dirty Hands
Mistake: Handling test strips with unclean hands can transfer oils, dirt, or moisture to the strips, potentially contaminating them and affecting results.
How to Avoid It:
- Wash Your Hands: Always wash and dry your hands thoroughly before handling test strips. This reduces the risk of contamination and ensures accurate readings.
5. Applying Too Much or Too Little Blood
Mistake: Applying too much or too little blood to the test strip can result in inaccurate readings. Strips are designed to process a specific amount of blood.
How to Avoid It:
- Follow Instructions: Adhere to the instructions for blood sample size provided with your test strips. Most meters will indicate if the sample is insufficient or excessive.
- Practice Technique: If you’re unsure of the right amount of blood, practice on a test strip that you don’t need to use for actual testing, if your meter allows it.
6. Reusing Test Strips
Mistake: Some people may attempt to reuse test strips, which can lead to incorrect results due to contamination or degradation of the strip.
How to Avoid It:
- Use a New Strip Each Time: Always use a fresh test strip for each blood glucose test. Reusing strips can compromise accuracy and reliability.
7. Not Calibrating the Meter Properly
Mistake: Failing to calibrate your glucose meter according to the manufacturer’s instructions can result in inaccurate readings.
How to Avoid It:
- Regular Calibration: Ensure your meter is calibrated correctly and as recommended by the manufacturer. Check the meter’s manual for specific calibration instructions.
- Professional Assistance: If you’re unsure about calibration, consult with your healthcare provider or the meter’s customer support for guidance.
8. Ignoring Error Codes
Mistake: Ignoring error codes displayed on your glucose meter can lead to inaccurate results or indicate that something is wrong with your testing process.
How to Avoid It:
- Review Error Codes: If your meter displays an error code, refer to the user manual to understand the issue and how to resolve it.
- Seek Help if Needed: Contact customer support or your healthcare provider if you frequently encounter error codes or if you’re unsure how to address them.
Avoiding these common mistakes with diabetic test strips can help ensure that you get accurate and reliable blood glucose readings. By following proper usage and storage guidelines, adhering to your meter’s instructions, and handling test strips with care, you can effectively manage your diabetes and make informed decisions about your health. If you have any concerns or need further assistance, don’t hesitate to reach out to your healthcare provider or the manufacturer for support.
