In the event of reading issues with my Sensor or my scanned reading does not match how I feel, should I do a blood glucose test with any blood glucose meter or does it have to be with a FreeStyle system?
When blood glucose is changing rapidly, we recommend that you verify the results with a fingerstick glucose test using a monitor of your choice. It is not mandatory that you use an Abbott-manufactured BGM device to check accuracy of the FreeStyle Libre system. You should always use a fingerstick test to confirm Sensor readings indicating hypoglycaemia or impending hypoglycaemia. Similarly, whenever your symptoms do not align with the FreeStyle Libre system reading, you must check your blood glucose using a fingerstick test. Contact your health care professional, if needed.1
