Freestyle Libre Sensor Error: “Try Again in 3 Hours” Explained
Have you encountered the dreaded “Try Again in 3 Hours” error while using your Freestyle Libre sensor? Don’t worry; you’re not alone. This error can be frustrating, but it’s important to understand what causes it and how to resolve it. In this comprehensive guide, we’ll delve into the reasons behind this error and provide step-by-step instructions on how to fix it.
Reasons for the “Try Again in 3 Hours” Error
The Freestyle Libre system uses a small sensor worn on the back of the upper arm to continuously monitor glucose levels. When the sensor is first inserted, it undergoes a warm-up period of approximately 12 hours. During this time, the sensor stabilizes its readings, and the system calibrates itself to provide accurate results. If a reading is attempted before the warm-up period is complete, the system will display the “Try Again in 3 Hours” error.
Sensor Insertion Errors
In some cases, the “Try Again in 3 Hours” error can occur due to improper sensor insertion. Ensure the sensor is inserted perpendicularly into the back of the upper arm and that the inserter is held firmly against the skin. Avoid reinserting the sensor multiple times, as this can damage the sensor or the insertion site.
Sensor Malfunctions
While rare, sensor malfunctions can also trigger the “Try Again in 3 Hours” error. If you suspect a sensor malfunction, remove the sensor and contact Abbott customer support. They will guide you through the process of replacing the sensor.
Tips and Expert Advice
- Wait for the Warm-Up Period:
Ensure you wait a full 12 hours after sensor insertion before attempting a reading. This allows the sensor to stabilize and calibrate properly.
- Check Sensor Placement:
Make sure the sensor is inserted correctly and perpendicularly into the back of the upper arm. If the sensor is not inserted properly, it may not read glucose levels accurately.
- Avoid Multiple Insertions:
Refrain from inserting the sensor multiple times into the same site. Doing so can damage the sensor or the insertion site, leading to inaccurate readings or error messages.
- Contact Customer Support:
If you repeatedly encounter the “Try Again in 3 Hours” error or suspect a sensor malfunction, contact Abbott customer support. They can assist in troubleshooting the issue and provide a replacement sensor if necessary.
- Use a Different Sensor:
If possible, try using a different Freestyle Libre sensor. This can help determine if the error is related to a specific sensor or if it’s a more widespread issue.
Frequently Asked Questions
- Can I use a Freestyle Libre sensor after 12 hours?
- Yes, after a 12-hour warm-up period, the sensor is calibrated and ready to provide accurate glucose readings.
- What should I do if I get the “Try Again in 3 Hours” error multiple times?
- Contact Abbott customer support. They can assist in troubleshooting the issue and provide a replacement sensor if necessary.
- Can I reinsert a Freestyle Libre sensor?
- No, Freestyle Libre sensors are designed for single use and should not be reinserted.
- How long does a Freestyle Libre sensor last?
- Freestyle Libre sensors have a life span of 14 days. Once the 14-day period has passed, the sensor should be removed and replaced with a new one.
Conclusion
The Freestyle Libre “Try Again in 3 Hours” error is typically caused by improper sensor insertion or a premature reading attempt before the warm-up period is complete. By following the tips and expert advice outlined in this guide, you can avoid or resolve this error and ensure accurate glucose monitoring with your Freestyle Libre sensor.
