Abstract:
A single-use electronic device for performing a coagulation or lysis assay of a blood sample, the device comprising:a housing having an exterior surface and defining an interior area;means for receiving the blood sample through the housing into the interior area;a non-porous substrate positioned within the interior area for receiving the blood sample thereon;a reagent for accelerating the coagulation of the blood sample positioned on the substrate and in contact with the blood sample;an electroactive species positioned on the substrate and in contact with the blood sample;means for measuring the viscosity of the blood sample and generating an electrical signal which correlates to a curve of a coagulation or lysis assay;processing means being positioned within the interior area and connected to the measuring means for receiving and converting the electrical signal into a digital output corresponding to the coagulation or lysis assay using assay calibration information stored in the processing means; anddisplay means for visually displaying the digital output external to the housing, the display means being connected to the processing means.
