Additional Details:

• Measures glucose accurately every minute. 40-400mg/dL range2

Freestyle Libre 2 has been cleared by the FDA to be worn during radiologic studies including X-ray imaging, computed tomography (CT), and magnetic resonance imaging (MRI).

• There is no waiting period after a CT-scan or X-ray to be able to safely use the FreeStyle Libre system sensor.
• MRI conditions: Depending on the type of  MRI procedure and scan required, there is potential for the accuracy and functionality to be compromised, so it is best to wait 1 hour following MRI exposure to ensure the FreeStyle Libre systems sensor is operating normally. After 1 hour, the accuracy and functionality of the device is not compromised.
• Fluoroscopy will have no impact on the sensor performance.
• There are no contraindications, warnings and limitations regarding use with ultrasound procedures. 
• The contraindication related to diathermy therapy remains unchanged.
• FreeStyle Libre Systems have not been studied with PET scan procedures; therefore, Abbott is unable to attest to the accuracy or performance of the Systems under such use case conditions.
• The users phone and reader must be left outside of the exam room.
