Advanced Tips And Tricks


When using the Freestyle Libre 3, it’s essential to have a continuous and reliable signal to ensure accurate glucose monitoring. However, signal loss can sometimes occur, leading to temporary interruptions in data transmission. In this section, we will discuss some advanced tips and tricks to help you troubleshoot and overcome signal loss issues, allowing you to make the most out of your Freestyle Libre 3 system.

Managing Signal Loss In Specific Situations

Signal loss can happen in different environments or situations, but with some careful adjustments, you can minimize its impact. Here are some tips:

  1. Ensure the sensor patch is securely attached to your skin. Loose patches can interfere with the signal transmission, leading to signal loss.
  2. Avoid placing any physical barriers between the sensor and the reader. Objects like clothing, metal objects, or even your body can obstruct the signal and cause disruptions.
  3. Keep the reader within an optimal range from the sensor. Ideally, the reader should be no farther than 1-2 inches away from the sensor to maintain a strong signal.
  4. Reduce interference from electromagnetic sources. Electronics like cell phones, laptops, or other wireless devices can interfere with the signal. Keeping these devices away from the reader can help minimize signal loss.

Extending Sensor Life For Continuous Monitoring

One of the main concerns with continuous glucose monitoring systems is sensor life. Fortunately, there are some tricks you can employ to extend the lifespan of your Freestyle Libre 3 sensor. Try the following:

  • Avoid excessive moisture around the sensor. While the Freestyle Libre 3 is water-resistant, excessive moisture can still impact its performance. Keep the sensor dry and avoid submerging it in water for extended periods.
  • Protect the sensor from extreme temperature conditions. Exposure to extreme heat or cold can affect its accuracy and longevity. Keep the sensor at optimal temperatures to ensure reliable readings.
  • Perform regular skin care around the sensor site. Maintaining clean and dry skin, free from oils, lotions, or adhesive residues, can promote better adhesion and prevent premature sensor detachment.
  • Consider using protective overlays or adhesive patches. These accessories can provide an extra layer of protection, minimizing wear and tear on the sensor and helping to extend its life.

Seeking Professional Assistance

Seeking professional assistance may be necessary when troubleshooting signal loss issues with the Freestyle Libre 3 system. While there are several steps you can take on your own to address the problem, contacting customer support or consulting with a healthcare provider can provide additional guidance and expertise.

When To Contact Customer Support

If you have been experiencing persistent signal loss with your Freestyle Libre 3 device, it may be time to reach out to the manufacturer’s customer support team. They can assist you in troubleshooting the issue and provide you with further recommendations to resolve the signal loss problem.
