Abstract
The system includes: an assortment (10) of sensors (10a, 10b, 10c), wherein the working electrode (14a) of each sensor is covered with a specific reagent of a given proteolytic enzyme, including a substrate capable of releasing leaving groups (LG) via the action of the enzyme; a measuring apparatus (20) having an electronic circuit imposing a current, whose intensity or voltage may or may not be variable, between the electrodes, and for receiving in return a signal representative of the release of the LG; and an electronic apparatus (30) for processing the transmitted signal and displaying, on a display screen (32), an indication representative of the release of the LG as a function of time. The system may be used to determine, in a plasma or whole blood sample, factors responsible for a coagulation anomaly.
