A diagnostic apparatus and method for clamping the blood glucose concentration of a subject at any one of a plurality of levels. A desired clamping level (BC) is selected and the value of the present blood glucose concentration, corrected to fit a least squares regression lines (GY) in the bloodstream of the subject is periodically determined. Dextrose is introduced into the bloodstream of the subject at a rate (DR) derived in accordance with ##EQU1## wherein: DR=dextrose infusion rate for clamp (mg/min)

Diagnostic method and apparatus for clamping blood glucose concentration

In a method and apparatus for controlling the concentration of glucose in the blood stream of a subject at a desired level (BI) including controlling the supply of insulin (IR) by periodically measuring the blood glucose concentration (G) and selecting a predetermined basal infusion rate (RI) for the desired level, the step of selecting a predetermined basal infusion rate comprises periodically searching for the value of the basal infusion rate RI required for BI in accordance with
