Corrected method for analysis of intravenous glucose tolerance test (IVGTT) data is proposed that simultaneously estimates the rate of glucose disappearance from the blood (k-value) and the index of hepatic glucose production (HGP) during test. In an application of the method to IVGTT data for 107 subjects, 27 diagnosed with type 2 diabetes (T2D), 13 with type 1 diabetes (T1D) and 67 healthy volunteers. Based on application of mathematical model of IVGTT data, two discriminating functions were obtained: distinguishing T2D from non-diabetic subjects and distinguishing T1D from T2D subjects. The 9% of non-diabetic subjects with high HGP estimates also had high k-parameter estimates. This is a pathological condition called �??�??impaired glucose balance�??�?? (IGB) and could be considered as the earliest, pre-impaired glucose tolerance (pre-IGT) and pre- impaired fasting glucose (pre- IFG) stage of T2D. One can distinguish four variants of glucose disbalance in overt diabetics depending on the k and H parameter values. It is apparent that seven subtypes of overt diabetes can be distinguished when one considers a combination of four types of glucose disbalance and two types of diabetes. It is assumed that various subtypes may be expected to respond in different manner to therapeutic interventions.
