The range for the ONE TOUCH® Normal Glucose Control Solution— Blue Formula is printed on the Test Strip vial or the foil wrapper. This range is for the Glucose Control Solution only; it is not intended as a recommended range for your blood glucose test results.
CAUTION: If your Control Solution result falls outside the printed range, the system is not working properly. DO NOT use the system to test your blood until you get a reading that falls within the printed range. For assistance, call LifeScan Technical Services.
You should use the Glucose Control Solution:
■At least once a week.
■When you begin using a new package of Test Strips.
■Whenever you suspect the Meter or Test Strip may not be working properly (for example, when your results are not consistent with how you feel).
