Lifescan - Onetouch Fasttake Control Solution Glucose Spec Storage - 12month Shelf Life, 2 Units / 1 unit

Control Solution is used to test the accuracy of your meter and test strips. Applied to a test strip, control solution confirms that the meter's test results are in the expected range printed on the test strip vial. Control solution tests should be performed at least once a week, every time a new vial of test strips is opened, and whenever you suspect the meter or test strips may not be functioning properly. Using the control solution is also recommended for teaching or learning how to test with your OneTouchr Blood Glucose Monitoring System.
