Control Solution Testing - Abbott FreeStyle Libre 2 User Manual

Accuracy of the Reader's built-in meter
Results from the Reader's built-in meter may vary slightly from your
actual blood glucose value. This may be due to slight differences in
technique and natural variation in test technology. The table below
shows the results of a study where 119 typical users used the built-in
meter to check their blood glucose level. For example, in the study, the
built-in meter gave results within 15% of true blood glucose level 115
out of 119 times.

Control Solution Testing

You should do a control solution test when you are not sure of your test
strip results and want to check that your Reader's built-in meter and test
strips are working properly.
IMPORTANT:
•
Control solution results should fall within the control solution range
printed on the test strip instructions for use.
•
Do NOT use control solution past the expiration date. Discard
control solution 3 months after opening or on the expiration date
printed on the bottle, whichever comes first. (Example: open April
15, discard July 15; write the discard date on the side of the bottle.).
•
The control solution range is a target range for control solution
only, not for your blood glucose results.
•
The control solution test does not reflect your blood glucose level.
•
Use only MediSense (low, medium or high) Glucose and Ketone
Control Solution with the Reader's built-in meter.
•
Check that the LOT number printed on the test strip foil packet and
instructions for use match.
•
Replace the cap securely on the bottle immediately after use.
•
Do NOT add water or other liquid to the control solution.
•
Contact your FreeStyle Libre 2 System provider (pharmacy or mail
order supplier) for how to obtain control solution.
