Forearm testing is most appropriate for your patients prior to, or more than two hours after meals, insulin dose or physical exercise.

Your patients should use their fingertip when testing within two hours after meals, an insulin dose or physical exercise, or whenever glucose levels may be changing rapidly.

When initiating post-prandial forearm testing with your patients, instruct them to obtain finger results in conjunction with forearm results to help assess whether the site to site differences are significant for each patient.
