Managing Type 1 diabetes is a constant balancing act, and at the heart of it lies regular blood sugar monitoring. For individuals with this condition, test strips are indispensable tools. These small, seemingly simple devices are crucial for tracking glucose levels, allowing for informed decisions about insulin dosages, diet, and activity. Without regular testing using test strips, achieving optimal glycemic control – maintaining blood sugar within the target range – would be extremely difficult, potentially leading to severe health complications. This detailed monitoring ensures that individuals with Type 1 diabetes can proactively manage their health and live full, active lives. The precision they offer is not just about getting a number; it's about having the necessary information to keep your body functioning properly, preventing dangerous highs (hyperglycemia) and lows (hypoglycemia).
Why Test Strips Are Essential:
- Real-time data: They provide immediate feedback on your current glucose level, which is crucial for making quick decisions regarding insulin dosing.
- Trend identification: Regular testing with test strips helps you see patterns, revealing how food, activity, stress, and illness impact your blood sugar.
- Personalized management: By understanding these patterns, you can tailor your diabetes management to your individual needs, rather than relying on general guidelines.
- Preventing complications: Monitoring with test strips is the primary method of preventing both acute and long-term complications of diabetes, including ketoacidosis (DKA) and nerve damage.
| Importance | Explanation |
|---|---|
| Real-Time Insights | Provides immediate blood glucose levels, enabling quick adjustments to insulin and diet. |
| Trend Tracking | Helps identify how daily routines affect blood glucose, which aids in personalized management. |
| Prevention of Complications | Regular use helps reduce risks of hypo/hyperglycemia and long term diabetes related complications. |
Understanding the Different Types of Blood Glucose Test Strips
Not all test strips are created equal, though they work by the same general principle: a drop of blood is placed onto the strip, which contains chemicals that react with the glucose, generating a tiny electric current that is then measured by a meter. Various brands offer test strips that vary slightly in how they work and other factors such as cost and specific meter compatibility. This makes choosing the right strip is a crucial step in ensuring accuracy and efficacy. Here, we will look into some different aspects.
Key Differences to Consider:
- Meter Compatibility: Each test strip is designed to work with a specific blood glucose meter. It is paramount to ensure your test strips and meter are compatible. This prevents inaccurate readings that can have dangerous implications. Using strips that are not made for your meter can cause false results.
- Required Blood Volume: Some strips need a smaller sample of blood than others. This is significant for individuals who may find it challenging to get a large drop of blood. Generally, modern test strips require only a very tiny drop. The required volume may also be different for certain continuous glucose monitoring (CGM) systems.
- Coding Requirements: Some older glucose meters require a manual code input each time a new batch of test strips is used, ensuring calibration with that specific strip lot. Nowadays, many modern meters will have an automated calibration. For convenience, automatic code strips may be worth looking for.
- Reaction Time: This can also vary between strips; the reaction time determines how quickly the result is displayed on the meter. Faster reaction times improve the workflow and daily routine and are generally preferred for monitoring needs.
- Accuracy Standards: While most strips adhere to ISO standards, slight differences in precision can occur. If the test strips are not of a reliable brand, or haven't been properly stored, there can be wide margins of error.
- Cost: The cost can vary by brand and supply contract. This makes it essential to check your insurance coverage or healthcare policy regarding availability of specific brands before choosing.
- Ease of Handling: Especially important for young children or older adults; consider size and ease of handling for test strips. Some may have a larger size, or an easier area to hold that may make the testing procedure less stressful.
| Feature | Explanation | Importance |
|---|---|---|
| Meter Compatibility | Ensuring that strips are designed for your specific meter model | Essential for accurate readings |
| Blood Sample Volume | Volume of blood needed to read glucose reading | Important for ease of use, particularly for children |
| Coding | Code calibration required for calibration or not, manual or automatic | Calibration impacts the meter results |
| Reaction Time | Time taken to show reading | Faster reading times allow for a better workflow |
| Accuracy | How accurate the strips perform | Essential for informed treatment decisions |
Best Practices for Using Blood Glucose Test Strips
Using test strips correctly is paramount to getting reliable and accurate results. Here are some best practices for you to keep in mind:
- Check Expiry Date: Always check the expiration date printed on the box before use. Expired strips may give inaccurate readings. Expired test strips must be avoided at all times.
- Proper Storage: Keep strips in their original container in a cool, dry place. Do not expose them to excessive heat or moisture, as that could degrade them. Avoid storing in places such as a hot car, bathroom, or near a radiator. Keep the container tightly sealed when not in use.
- Hand Hygiene: Always wash your hands thoroughly with soap and water before testing. Ensure your hands are fully dry before testing, as traces of moisture can cause an unreliable reading.
- Proper Blood Application: Get a small but sufficient drop of blood, and gently apply to the marked area of the test strip. Make sure that the blood sample fills the window and not directly applied outside it, otherwise it could cause an inaccurate reading.
- Consistent Testing Times: Try to test your blood sugar at similar times each day, so you can more accurately track your progress, along with changes based on exercise and dietary intake. Work with your health professional to set a personalised blood glucose testing routine.
- Record your readings: Keeping a record of your readings, together with information about meals, exercise and other activities, will help your healthcare provider in assessing your diabetes care and recommending any needed adjustments. You may want to use a dedicated glucose meter diary, a notebook, or a mobile phone app to record readings.
- Quality Control Testing: If the meter you are using requires a QC test, ensure you are using the proper control solution with your test strips from the same manufacturer to regularly check your meter is working properly. Follow the manufacturers guidelines exactly for QC test requirements.
Step-by-Step Guide for Using Test Strips:
- Gather supplies: Wash hands, gather your glucose meter, a new test strip, lancing device (with a fresh lancet), and your chosen logbook or application.
- Insert a test strip: Insert the new test strip into the glucose meter. Turn it on if it does not power on automatically.
- Prepare your finger: Prick the side of your fingertip with the lancet using your lancing device to produce a small drop of blood.
- Apply blood to strip: Bring the edge of the test strip to the blood, drawing it to the designated area of the strip to be absorbed. Wait until the meter completes its reading.
- Record results: Record the blood sugar result in your diary or application and dispose of the used lancet and test strip correctly.

Continuous glucose monitoring (CGM) systems are becoming increasingly common, providing continuous readings throughout the day without the need for constant finger pricks. While CGMs are a major development, test strips remain relevant for some patients.
- Calibration of CGM: Test strips may still be required periodically to calibrate some types of CGMs or to cross-check a reading when the sensor might be less reliable.
- Back-Up System: When a CGM fails or is unavailable for use for a variety of reasons, the use of test strips to monitor glucose levels can be critically important to ensure glycemic control.
In the future, there may be a better integrated system that allows test strips and CGM to work alongside each other, and in certain circumstances use both simultaneously to allow more insights and accuracy when monitoring blood glucose. As technology evolves, so will test strips along with other aspects of glucose monitoring, improving the lives of those living with Type 1 diabetes.
Source: One of the chronic issues I suffered with for many years was reactive hypoglycemia. All through my teens and most of my 20’s I couldn’t go more than 2.5 to 3 hours between meals without getting dizzy and hangry. It really was annoying and interfered with me living my life. I had to constantly make sure I brought plenty of blood sugar and caffeine snacks and if I couldn’t bring snacks, where the closest food was so that I wouldn’t have to stop was I was doing until my blood sugar went back up. In today’s episode, I am going to share with you the strategies I’ve learned through my research and then self-testing to keep my blood sugar on a gentle wave instead of huge spikes and massive drops throughout the day. I want you to break this cycle too and have stable energy all day long. ~Marian ****************************************************** Get Started Guide: Therapeutic Food Framework: Join the Community: Follow on Insta: Disclaimer: The goal of this podcast is to help you take control of your health and feel the best you possibly can!
