Abstract: The present invention covers the integration and utility of accelerometer features into a clinical analysis system. For example, measurement of dynamic acceleration and orientation of a blood-testing instrument with respect to Earth's gravitational field may be used to determine reliability of a test procedure and optionally to provide corrective elements thereof.

Abstract: This invention is a disposable cartridge for use at the patient side to perform traditional coagulation assays on fresh whole blood or blood derivative samples. The cartridge, in use with an electronic analyzer allows a fluid sample to be metered and quantitatively mixed with reagents which activate the coagulation cascade. An artificial substrate for thrombin, the enzyme whose action results in clot formation is also provided. Clot formation is subsequently detected using a microfabricated sensor also housed within the cartridge which detects electrochemically the product of the thrombin reaction upon the synthetic substrate.
