The acceptable range for OneTouch Ultra Control Solution is marked on the OneTouch Ultra Test Strip package. This range is for the Control Solution only; it is not a recommended range for your blood glucose test results.
Note: The Control Solution range is shown in two different units of measure--mg/dL and mmol/L, for use in different countries.
Control solution is used to check that both the meter and the test strips are working together as a system, and that you are doing the test correctly. Use only the OneTouch Ultra Control Solution for your OneTouch Ultra Meter. Control solution is available from Customer Care.
