Introduction

For individuals managing diabetes, understanding whether glucose monitoring tools work together is important. A common question is “Are true metrix test strips compatible with the Freestyle Libre system?”. This response provides a clear, formal explanation to address this question.

What Are True Metrix Test Strips?

True Metrix test strips are used with True Metrix blood glucose meters, such as the True Metrix Air or True Metrix Go. These strips require a small blood sample, typically from a fingerstick, which the meter analyses to display a blood glucose reading. The system is reliable, affordable, and widely used for traditional blood glucose monitoring.

What Is the Freestyle Libre System?

The Freestyle Libre, developed by Abbott, is a continuous glucose monitoring (CGM) system. It involves a small sensor placed on the skin, usually on the upper arm, that measures glucose levels in interstitial fluid throughout the day. Readings are shown on a dedicated reader or a compatible smartphone. Models like the Freestyle Libre 2 and 3 reduce the need for frequent fingerstick tests, offering convenience and detailed glucose trends.

Compatible with Freestyle Libre?

True Metrix test strips are not compatible with the Freestyle Libre system. The reasons for this include:

1. Different Methods: True Metrix test strips are designed for single blood glucose tests using a blood sample, while the Freestyle Libre continuously monitors interstitial glucose with a sensor. These approaches are not interchangeable.
2. Device-Specific Design: True Metrix test strips work only with True Metrix meters. The Freestyle Libre does not use test strips; instead, it relies on its sensor, reader, or smartphone.
3. Manufacturer Standards: Abbott (Freestyle Libre) and Trividia Health (True Metrix) create products to function within their systems to ensure accuracy and meet regulatory requirements. Combining them is not supported.

Use True Metrix and Freestyle Libre Together?

Although True Metrix test strips cannot be used with the Freestyle Libre system, both can be part of a comprehensive diabetes management plan. For example:

• Freestyle Libre for Continuous Monitoring: The CGM provides ongoing glucose readings, helping track trends and patterns.
• True Metrix for Occasional Checks: Using True Metrix meters with test strips allows for fingerstick tests to confirm CGM readings, especially during rapid glucose changes or if sensor results seem unclear.

This combination can provide a complete picture of glucose levels by blending the ease of continuous monitoring with the reliability of traditional testing.

Alternatives for Freestyle Libre Users

For those using Freestyle Libre who need a fingerstick testing option, the following

• Freestyle Lite Test Strips: Also made by Abbott, these strips work with Freestyle Lite or Freestyle Freedom Lite meters, making them a natural fit for Freestyle Libre users.
• Other CGM Systems: Systems like the Dexcom G7 or Medtronic Guardian Connect offer continuous monitoring and may meet specific needs.
• Consult Your Doctor: A healthcare provider can recommend the best tools based on your medical needs and lifestyle.

Advantages of True Metrix Test Strips

True Metrix test strips are a strong choice for traditional glucose monitoring:

• Accurate results for dependable readings.
• More affordable than CGM systems.
• Simple to use with True Metrix meters.

Advantages of Freestyle Libre

The Freestyle Libre system offers unique benefits for continuous monitoring:

• Fewer fingerstick tests, easing discomfort.
• Detailed glucose trends to guide decisions.
• Convenient with minimal equipment.

Conclusion

True Metrix test strips are not compatible with the Freestyle Libre due to differences in how they work, their design, and manufacturer standards. However, they can be used together in a diabetes management plan, with Freestyle Libre offering continuous monitoring and True Metrix providing occasional fingerstick tests. For a fingerstick option within Abbott’s system, Freestyle Lite test strips are a good choice. Speak with your healthcare provider to create a monitoring plan tailored to your needs, ensuring effective diabetes management.
