Common Mistakes When You Check Blood Sugar at Home (and How to Fix Them)
Managing diabetes often involves regular blood sugar monitoring at home. It's a crucial part of staying healthy, but mistakes can happen, leading to inaccurate readings and potentially impacting your treatment plan. This article explores common errors people make when checking their blood sugar at home and provides practical solutions to avoid them.
Why Accurate Blood Sugar Readings Matter
Accurate blood sugar readings are essential for several reasons:
- Adjusting Medication: Your doctor uses these readings to adjust your insulin dosage or other medications.
- Managing Diet and Exercise: Readings help you understand how different foods and activities affect your blood glucose levels.
- Preventing Complications: Consistent monitoring helps you stay within your target range, reducing the risk of long-term diabetes complications.
Common Mistakes and How to Fix Them
Let’s dive into some of the most frequent mistakes people make and, more importantly, how to rectify them.
1. Not Washing Your Hands Properly
This is one of the most overlooked yet crucial steps. Dirty hands can contaminate the sample, leading to falsely high readings. Even seemingly clean hands can have traces of food residue that can affect the results.
- The Fix: Always wash your hands thoroughly with soap and warm water before testing. Dry them completely with a clean towel. Avoid using alcohol-based hand sanitizers, as they can sometimes interfere with the test.
2. Using Expired or Damaged Test Strips
Test strips have an expiration date, and using expired strips can lead to inaccurate readings. Additionally, strips that have been exposed to moisture or extreme temperatures may not work correctly.
- The Fix: Always check the expiration date on your test strip container. Store your test strips in a cool, dry place, away from direct sunlight and humidity. If the container is damaged, discard the strips.
3. Using the Wrong Test Strip for Your Meter

- The Fix: Always use the test strips designed for your specific meter. Double-check the compatibility of the strip and meter, especially when purchasing new strips. When in doubt, consult your meter's manual or ask your pharmacist.
4. Not Using Enough Blood
Insufficient blood can lead to an error message or a falsely low reading. Some meters require a larger blood sample than others.

- The Fix: Ensure you are using enough blood to completely fill the test strip's sample area. If you are having trouble getting enough blood, try gently massaging your finger towards the puncture site. You can also try warming your hands before testing. Using a lancing device with adjustable depth settings can also help.
5. Puncturing the Finger Incorrectly
Puncturing the finger in the wrong spot can also affect the amount of blood obtained and the accuracy of the reading.
- The Fix: Prick the side of your fingertip rather than the pad. The sides of the fingertips are less sensitive and provide better blood flow. Rotate your fingers regularly to avoid soreness.
6. Not Calibrating the Meter
Some blood glucose meters require calibration with a control solution. This ensures the meter is working correctly.
- The Fix: Follow the instructions in your meter's manual to calibrate it regularly, especially when you open a new container of test strips. Use the control solution specifically designed for your meter.
7. Ignoring Meter Error Messages
Ignoring error messages from your blood glucose meter can lead to incorrect results. Error messages often indicate a problem with the test strip, the meter itself, or the testing process.
- The Fix: Always pay attention to error messages. Refer to your meter's manual to understand the meaning of each error message and how to resolve the issue. If you are unable to resolve the issue, contact your healthcare provider or the meter manufacturer.
8. Testing Too Soon After Eating or Exercising
Testing your blood sugar immediately after a meal or strenuous exercise may not provide an accurate representation of your typical levels.
- The Fix: Follow your doctor's recommendations regarding when to test your blood sugar. Generally, testing before meals, two hours after meals, and at bedtime is recommended. Understand how your body responds to different types of food and exercise, and adjust your testing schedule accordingly in consultation with your healthcare team.
9. Not Storing Your Meter and Supplies Properly
Improper storage can damage your meter, test strips, and other supplies, leading to inaccurate readings.
- The Fix: Store your meter and supplies in a cool, dry place, away from direct sunlight and humidity. Keep them in their original packaging to protect them from damage. Avoid storing your meter in the bathroom or other humid environments.
Troubleshooting Common Issues
Here's a quick guide for addressing some recurring problems:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent Readings | Improper technique, expired strips, meter malfunction | Review technique, check strip expiration, calibrate meter, contact manufacturer if necessary. |
| Error Messages | Strip error, meter malfunction, insufficient blood | Replace strip, review technique, ensure sufficient blood sample, consult meter manual. |
| Difficulty Obtaining Blood | Cold hands, shallow puncture, dehydration | Warm hands, increase puncture depth, stay hydrated. |
The Importance of Routine Maintenance and Calibration
Regular maintenance of your blood glucose meter is essential for ensuring accuracy and longevity. This includes cleaning the meter, calibrating it with control solutions, and replacing any worn-out parts. Always refer to the manufacturer's instructions for specific maintenance recommendations.
