Abstract: An improved quality assurance system and method for point-of-care testing are disclosed. The present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care without the need for running liquid-based quality control materials on the analysis system. Quality assurance of a quantitative physiological sample test system is performed without using a quality control sample by monitoring the thermal and temporal stress of a component used with the test system. Alert information is generated that indicates that the component has failed quality assurance when the thermal and temporal stress exceeds a predetermined thermal-temporal stress threshold. Alternatively, the present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care by minimizing the need for running liquid-based quality control materials on the analysis system.

Abstract: Methods and devices for determining sensing device usability, e.g., for point of care immunoassay devices. In one embodiment, the invention is to a method of determining device usability, comprising the steps of providing a device comprising a first electrical pad; a second electrical pad; and a continuous polymer layer contacting at least a portion of the first and second electrical pads; applying a potential across the first and second electrical pads; measuring an electrical property associated with the continuous polymer layer; and determining whether the measured electrical property associated with the continuous polymer layer has exceeded a threshold level associated with the device usability.

Abstract: Methods and devices for correcting sensing device signals, e.g., for point of care immunoassay devices. In one embodiment, the invention is to a method of correcting a signal in a sensing device, comprising the steps of: providing a sensing device comprising a sensor, a first electrical pad, a second electrical pad, and a continuous polymer layer contacting at least a portion of the first and second electrical pads; applying a potential across the first and second electrical pads; measuring an electrical property associated with the continuous polymer layer; determining a correction factor associated with the measured electrical property; and applying the correction factor to a signal generated by the sensor to produce a corrected signal.
