Each vial of OneTouch Verio® control solution has the range printed on its label. Compare the result displayed on the meter to the range printed on your OneTouch Verio® Control Solution vial.
If your control solution result falls outside the expected range, repeat the test with a new test strip. If you continue to get control solution results that fall outside the range printed on the control solution vial, Do Not use the meter, test strips, or control solution.
