Hi @dorisena. You are doing a great job keeping your blood glucose low. The hemoglobin A1C test gives you and your physician the accurate reading for the past three months. I have never seen a meter not requiring to use a control solution to test the machine. Machines will likely break down eventually. I understand you are careful with maintaining low blood sugars but not everyone follows the same regimen. Look at the owner’s manual for the Freestyle Lite. The following page 11 of the manual outlines the information:

Important Control Solution Information
FreeStyle® Control Solution is good for three months after opening the bottle or until the expiration date printed on the label, whichever comes first.
Important: Count forward three months from the date you open a new bottle of control solution. This is your discard date. Write this date on the side of the control solution bottle.
Example: You open the control solution on January 15th. Count forward three months to April 15th. This is the discard date that you record on the bottle.

• Ifyourcontrolsolutiontestresultscontinuetofalloutsidetherange printed on the test strip vial, do not use the FreeStyle Lite System to test your blood glucose. Contact Customer Care.
Caution: Results from FreeStyle Control Solution tests do not reflect your blood glucose level.

Hope this is helpful. Toni
