FORA blood glucose meter systems allow you to obtain a blood sample from an alternative site such as your palm, forearm, or upper arm. Notice: alternative site testing is not fit for everyone. It may have some limitations if you have just taken insulin and: • You think your blood glucose is low. • The test results do not agree with how you feel. • You have an ill feeling. • You are unaware of the symptoms when you become hypo glycemic. Alternative site results may be different than those from the fingertips when blood glucose levels are changing rapidly, such as after a meal or during and after exercise.
