A method of screening for disorders of glucose metabolism such as impaired
glucose tolerance and diabetes allows prevention, or early detection and
treatment of diabetic complications such as cardiovascular disease,
retinopathy, and other disorders of the major organs and systems. A
mathematical algorithm evaluates the shape of a subject's glucose profile
and classifies the profile into one of several predefined clusters, each
cluster corresponding either to a normal condition or one of several
abnormal conditions. The series of blood glucose values making up the
glucose tolerance curve may be measured using any glucose analyzer
including: invasive, minimally invasive and noninvasive types. The method
is executed on a processing device programmed to perform the steps of the
method. Depending on the outcome of the screening, a subject may be
provided with additional information concerning their condition and/or
counseled to consult further with their health care provider.
