Blood glucose monitoring lets you know what your blood glucose level is at the time of testing. The reading provides helpful information on how well you are managing your diabetes. Keeping your blood glucose level within the target range set by you and your doctor reduces the risk of diabetes complications. It is important to check your blood glucose regularly so you can see how certain foods, activities and medicine affect your blood glucose level.
