Cartridge device identification for coagulation assays in fluid samples

A system for identifying an analyte measured with an integrated circuit chip, the system comprising:

• the integrated circuit chip, comprising
• a first amperometric electrode connected to a first connection pin;
• a reference electrode connected to a second connection pin;
• and
• a resistor with a predetermined resistance value that is connected between the second connection pin and a third connection pin;
• and
• a processor configured to measure a resistance between the second connection pin and the third connection pin, and compare the measured resistance to known values within an electronic look-up table to identify the analyte the chip measures,
• wherein the first amperometric electrode is a prothrombin time (PT) detection electrode or an activated partial thromboplastin time (aPTT) detection electrode, and
• wherein the first amperometric electrode comprises at least one transducer coated with a polymer layer, wherein the polymer layer comprises a thrombin-cleavable peptide with a detectable moiety.

A system of identifying a set of analytes measured with an integrated circuit chip, the system comprising:

• the integrated circuit chip, comprising
• a plurality of amperometric electrodes each connected to one of a plurality of first connection pins;
• a reference electrode connected to a second connection pin;
• and
• a resistor with a predetermined resistance value that is connected between the second connection pin and a third connection pin;
• and
• a processor configured to measure a resistance between the second connection pin and the third connection pin, and compare the measured resistance to known values within an electronic look-up table to identify the set of analytes the chip measures,
• wherein the plurality of the amperometric electrodes comprises at least one of a prothrombin time (PT) detection electrode and an activated partial thromboplastin time (aPTT) detection electrode, wherein each of the PT detection electrode and the aPTT detection electrode comprises at least one transducer coated with a polymer layer, wherein the polymer layer comprises a thrombin-cleavable peptide with a detectable moiety.
