Quality assurance system and method for point-of-care testing
First Claim
1. A system for performing quality assurance of a quantitative physiological sample test system without using a quality control sample, comprising:
- a sample testing cartridge comprising;
a port configured to receive a physiological sample; and
a sensor configured to detect an analyte in the physiological sample;
a reader comprising;
a port configured to receive the sample testing cartridge; and
a processor configured to;
receive a signal from the sensor when the sample testing cartridge is received by the port of the reader; and
generate test results based on the signal;
a thermal and temporal stress monitor module configured to;
monitor thermal and temporal stress of the sample testing cartridge;
register a shift in baseline calibration potential of at least one sensor based on the monitored thermal and temporal stress; and
communicate information regarding the shift in the baseline calibration potential when the sample testing cartridge is received by the port of the reader; and
a quality assurance failure alert module in communication with the thermal and temporal stress monitor module and configured to;
receive the information regarding the shift in the baseline calibration potential;
compare the information against an anticipated range;
generate alert information indicating that the sample testing cartridge has failed quality assurance when the information is outside of the anticipated range; and
suppress display of the test results on the reader when the sample testing cartridge has failed quality assurance.

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.
