A blood glucose meter gives you an immediate blood glucose result. Writing test results in a logbook and comparing them over time can show you and your healthcare professional if your diabetes management program is working for you or if you need to make adjustments. Keeping your log book up to date is also a great way to see how daily events like meals and exercise impact your blood glucose. For your convenience and to encourage better management of your diabetes, we provide the One Touch Logbook for you and your healthcare professional. The size of the OneTouch logbook is similar to a checkbook.
