Key Factors Affecting Accuracy in Blood Glucose Test Strips
The reliability of blood glucose readings at home hinges on more than just the meter used; it is equally about the quality and handling of test strips. Several factors can influence the accuracy of these strips, which is why understanding how they work and the factors impacting their function is essential for users.
One critical aspect is proper storage. Blood glucose test strips are generally sensitive to moisture, temperature, and exposure to air. Manufacturers typically recommend that strips be stored in a cool, dry place, away from direct sunlight, and within the specified temperature range provided in the packaging instructions. Deviations from these conditions can compromise the effectiveness of the chemical reagents within the strip, leading to inaccurate or false readings. This means that leaving strips exposed, carrying them in hot environments, or not sealing the container properly can all negatively affect results.
Another crucial element is strip compatibility. Test strips are designed to work with specific glucose meters. Incorrect use of incompatible strips can lead to either no reading at all or inaccurate results. Therefore, always make sure that you're using the strips that are specifically made for your glucose meter, which will be either indicated in the instruction manual for both your glucose meter and test strips. Moreover, expiry dates should never be overlooked. Using expired strips is a recipe for inaccurate readings because the chemical reagents on the strip degrade with time, reducing their sensitivity and affecting results significantly. It is vital to check expiration dates prior to each use and replace if expired.
| Factor | Impact on Accuracy | Recommendations |
|---|---|---|
| Storage Conditions | High temperatures/humidity can degrade reagents leading to false readings | Store in a cool, dry place away from sunlight. Seal container properly. |
| Compatibility | Using incorrect strips may not work or produce incorrect results | Always use strips designed for the specific meter. |
| Expiration Date | Using expired strips leads to incorrect results as the reagents lose efficacy | Check the expiry date before each use and discard if expired. |
| Handling | Touching the testing area, improper insertion, can contaminate the strips | Avoid touching the test area, insert strip straight into the device and follow the user guide |
| Environmental Factors | Exposure to extreme heat, cold or high altitude, can influence reading accuracy | Store, and test in a normal room temperature environment to get the most accurate reading |
Step-by-Step Guide for Using Blood Glucose Test Strips Correctly
Achieving accurate glucose readings using blood glucose test strips requires a consistent and methodical approach. Here’s a step-by-step guide that explains how to use these test strips properly, ensuring that you get the most precise results:
- Prepare your equipment: Make sure you have a clean lancing device and a compatible glucose meter ready. Then, remove a single test strip from its container. Always remember to close the container tightly to prevent any damage to remaining strips from the environment.
- Insert the strip: Carefully insert the blood glucose test strip into your meter’s testing port. Ensure that it fits securely and in the right direction as indicated in your meter's instructions. The meter should turn on automatically, or you may need to press a button to initiate it.
- Prepare your fingertip: Use an alcohol wipe or soap and water to thoroughly clean your fingertip at the site where you plan to prick. It’s best to prick the side of your fingertip where it is less sensitive. Ensure that the area has dried completely before pricking to prevent inaccurate readings caused by residual moisture or alcohol.
- Prick your finger: Position your lancing device against the clean side of your fingertip and press the trigger. Gently massage or apply slight pressure around the prick area to encourage a sufficient drop of blood to form.
- Apply the blood: Hold the test strip edge up to the blood drop gently. Allow the strip to absorb the blood sample according to your device specifications. Ensure that the sample drop is ample. Insufficient blood can cause inaccurate readings or errors.
- Wait for the result: The glucose meter will start analyzing the blood sample. Keep the device steady until the test is completed. The glucose meter screen will display your blood glucose reading after a few seconds, and the measurement will usually be stored in the device's memory.
- Discard the strip: Carefully remove and dispose of the used blood glucose test strip safely. Most often they are just tossed in the waste, but can also be disposed of in a bio-hazard container, depending on individual and/or municipal requirements.
- Record your result: You should keep track of your glucose measurements in a logbook, which will help you identify patterns and manage your treatment plan more effectively. This data is crucial to identify how various daily life activities influence your blood glucose levels.
By following this detailed procedure, you increase the chance of obtaining reliable and accurate readings and making timely and informed health management decisions.

Choosing the Right Blood Glucose Test Strips for Your Needs
Selecting the correct test strips is as crucial as the meter itself for reliable blood glucose readings. Several factors influence the choice, and understanding these can help you make an informed decision that suits your particular needs. Consider these key factors when choosing blood glucose test strips:
Compatibility with Your Glucose Meter: The most important factor is ensuring that the strips are fully compatible with your existing glucose meter. Different manufacturers use different technologies and strips are designed to be used specifically with one brand’s device. Always double-check your meter's manual for compatible test strips and never mix strip brands across meters. Incorrect use can either prevent readings, lead to inaccurate results or may damage your meter and may also void a meter's warranty.
Accuracy and Reliability: While all test strips must meet certain standards, it's prudent to consider brands known for consistency and accuracy. Independent evaluations or reviews, and those from professionals can give you an indication of quality and reliability. Remember, any brand will still be limited by user error, or improper handling and/or storage. A strip can be highly accurate, but that won't do any good if a user doesn't properly prepare and/or execute the test.
Cost: The price of test strips can vary significantly. If you are using test strips frequently, the cost can become a significant ongoing expense. Compare pricing among different brands while ensuring you’re not compromising on quality. Be mindful that cost does not always dictate the level of accuracy. Sometimes you pay for convenience such as individual packaging versus a bulk pack. Always evaluate overall cost on long term needs and not initial sticker shock.
Ease of Use: Some test strips are simpler to handle than others. Look for features such as a design that makes handling more secure with less chance of touching the blood-sensitive area. Larger strips can often be easier for users with dexterity issues or those with poor vision, making the testing process less complicated. Evaluate the handling before choosing a brand.
Availability and Convenience: Consider the ease with which you can access replacement strips. A product readily available at your local pharmacy will prevent last minute panics when supplies are running low. If not available, it can also help if you have an alternative and compatible test strip brand available.
Insurance and Reimbursement: Consult with your insurance provider to determine which brands or models are covered under your plan. Coverage can affect your choice, as can using the preferred brand may reduce cost. Also consult with your plan on quantity or prescription limitations for testing supplies.
