Step 1: Inserting a New Sensor

To begin, follow the manufacturer’s instructions and insert a fresh sensor into the designated area of your body. Pay attention to cleanliness and adhere to proper hygiene practices throughout this process.

Step 2: Activating the Sensor

Follow the directions provided by the manufacturer to turn on the sensor after it has been firmly installed. Typically, this involves initiating the sensor through the accompanying device or app.

Step 3: Conducting the Initial Calibration

Obtaining a Blood Glucose Reading Using a Reliable Meter

Utilize a dependable blood glucose meter to obtain an accurate reading of your blood glucose level. Ensure that the meter is properly calibrated and in optimal working condition.

Inputting the Meter Reading into the Freestyle Libre 14 Day Reader

Take the blood glucose reading obtained from the meter and input it into the Freestyle Libre 14 Day Reader or the designated device associated with the sensor. Follow the manufacturer’s instructions for this step.

Step 4: Continuous Monitoring and Additional Calibrations

Checking and Inputting Meter Readings at Regular Intervals

Continuously monitor your blood glucose levels using a reliable meter. Take readings at recommended intervals, as advised by your healthcare provider or the manufacturer’s guidelines.

Input the meter readings into the Freestyle Libre 14 Day Reader or the associated device when prompted or according to the provided instructions.

Calculating if Significant Deviations Occur

If substantial deviations arise between the meter readings and the readings from the Freestyle Libre 14 Day Reader, follow the manufacturer’s guidelines for calibrating the sensor. This may involve performing additional calibrations using reliable blood glucose meter readings to enhance accuracy.

Step 5: Properly Discarding the Used Sensor

Once the sensor has served its intended duration (14 days in the case of the Freestyle Libre 14 Day Reader), carefully remove and dispose of it according to the manufacturer’s instructions. 

Adhere to proper waste disposal guidelines and follow any specific instructions provided for sensor disposal.

Essential Tips for Accurate Calibration

Allow me to share some invaluable tips to ensure that your calibration efforts yield optimal results:

  • Choose Stable Periods for Testing: Test your blood glucose levels during stable periods when they are not fluctuating dramatically. Accuracy is easier to achieve when your levels are steady and consistent.
  • Avoid Calibrating During Rapid Changes: It is advisable to avoid calibrating your device during instances of rapid blood sugar changes. Trying to calibrate while your levels are in flux is akin to targeting a moving target. Give your body some time to stabilize before initiating the calibration process.
  • Invest in a Reliable Blood Glucose Meter: Do not compromise on the quality of your blood glucose meter. Investing in a reliable and accurate device is akin to having a dependable sidekick on your journey with diabetes. Make sure your meter is properly calibrated and functions optimally.
  • Double-Check Meter Readings: Before inputting the meter readings into your Freestyle Libre 14 Day device, take a moment to double-check them. As humans, we are prone to errors, and a little extra caution can go a long way in ensuring accurate calibration.

Troubleshooting Calibration Issues

Let’s address some common calibration hiccups and explore effective troubleshooting strategies:

  • Sensor Error Messages: Encountering sensor error messages can be as bothersome as a persistent fly buzzing around your head. If you come across such a message, there’s no need to panic. Refer to the user manual for guidance, or reach out to the helpful folks at customer support. They are there to lend a helping hand and assist you in resolving the issue.
  • Inaccurate or Unstable Readings: Dealing with inaccurate or unstable readings can be quite frustrating. However, fear not! Start by checking the placement of your sensor to ensure it is snug and secure. Consider external factors such as temperature or electromagnetic interference that may affect the readings. If everything else fails, never be afraid to call customer service. They possess the expertise to guide you out of those tight spots and help resolve the issue.
