According to Tyson Bio, Alternative site results differ from fingertip results when glucose levels are
changing rapidly such as after a meal, after taking insulin, during exercise,
or when you are ill or under stress. Use blood from a fingertip rather than an
alternative site if:
● you think your blood glucose is low,
● you don’t regularly have symptoms when your blood glucose is low, or
● how you feel doesn’t match the results from the alternative site.
● When you have just taken insulin, or any time during or after exercise.
● When there are unknown variables occurring in your day, such as illness.
● Whenever you are about to drive.
