Calibrate Your System/Test Blood Glucose Manually

 

Purpose Start

Materials

To ensure the receiver will calculate your glucose readings accurately.

Do this procedure:

Each time the receiver prompts you with the message, “Do BG Test.” You will

see a blood drop icon

on the screen and you will also hear the system beep

(or vibrate).

 

When you need to measure your blood glucose manually using the built-in

FreeStyle Meter.

Soap, water, and a clean towel. • FreeStyle Test Strips.

• A FreeStyle Lancing Device.

• Your FreeStyle Navigator Receiver.

• Sterile lancets.

• A sharps container.

Helpful Information

Important Things to Remember About System Calibration

The system is calibrated using a capillary whole blood glucose measurement (performed in the Blood Glucose mode using the built-in FreeStyle Blood Glucose Meter). In order to calibrate, the receiver compares the reading it gets from the blood to the reading the sensor takes from the interstitial fluid. Based on the calibration, the receiver calculates the glucose readings.

Do not use venous blood for calibrating the system.

Caution: Always calibrate the system only using a finger-stick blood sample. Do NOT use alternate site blood glucose measurements to calibrate the system. The receiver contains a built-in FreeStyle® Blood Glucose Meter for performing calibration tests.

Important: Your blood glucose level must be between 60 and 300 mg/dL (3.3 and 16.7 mmol/L) to be able to perform calibration tests. If your blood glucose level is changing rapidly, you may not be able to calibrate the system. For example, during a meal or exercise, your glucose levels may vary rapidly. Try to time your sensor insertion so that your calibration times do not coincide with your regular meal or exercise activities.

Important: In clinical trials, we observed that the sensor signal sometimes temporarily decreases from the true value. This typically happens at night during sleep, and recovers rapidly when the user moves or is awakened. However, in order to avoid being affected by this phenomenon the system should not be calibrated when the wearer is asleep.

You may not be able to calibrate the system if your glucose levels are changing rapidly (e.g. during or after exercise, meals or insulin dosing). Under such conditions, the system may not ask you to calibrate; instead, it will delay its request until conditions are acceptable.
