Abstract

Analytical system for monitoring patient blood concentration of a substance to be analyzed, comprising analysis-elements (12) containing reagents and an evaluation instrument comprising a measurement device to measure a change resulting from a reaction of the analyte with the reagents in order to determine, from the measurement values so obtained, analytical data representing element analysis data C.sub.A. In order to allow continuous monitoring of the analyte with good accuracy and a reduced number of invasive sample generation steps it is proposed that the analytical system further comprises (i) a sensor unit (2) portable on the patient body, said sensor unit (2) including a sensor (7) borne on the patient body for the direct and reagent-free measurement of a parameter correlating with the concentration of the analyzed substance and a transmitter for the wireless transmission of data signals; and (ii) a sensor-analysis means to ascertain sensor-analysis data C.sub.S from the measurement values of said parameter measured by said sensor; and the evaluation instrument further comprises a receiver to receive in wireless manner the data signals from the sensor unit (2), calibration me…
