CareSens Control Solutions are available to check the performance of your CareSens N, N POP, N Voice, and N Premier meters. Your local pharmacy may have controls and can perform this test for you. Alternatively, you can order controls (free of charge) and check your meter yourself..
The control solution test must be conducted at room temperature (20 - 25⁰C). It is recommended that the control solution is kept at room temperature for 30 minutes before testing. The control solution should be shaken well before use, and the first drop should be discarded and the dispenser top wiped clean prior to using the subsequent drop for the test.
Please note that once opened, the control solution will expire after 90 days.
