As an aid to subjects with DM1 for managing their blood glucose levels as close to normal as possible, blood glucose monitoring systems have been developed. Available blood glucose monitoring systems today require a capillary blood sample that is analysed by a glucose meter. Subjects are normally advised by health care professionals on the appropriate blood glucose monitoring regime for their condition. However, many subjects fail to measure blood glucose as often as needed to achieve good blood glucose control despite every effort from health care professionals.
