Checking your blood sugar is an essential part of diabetes management. Accu-Chek Guide control solutions are specifically designed to work with your Guide meter and strips. Perform a test with glucose control solution to confirm the accuracy of test results. Simply use the control solution instead of blood on a test strip. If the result matches the expected glucose level, your meter and test strips are working properly. For over 40 years, Accu-Chek has been a leader in providing convenient and accurate diabetic management supplies.
