The present invention relates generally to quality control systems, methods and computer readable media, and more particularly to a quality control system, method and computer readable medium for use with biological/environmental diagnostic test devices, users and consumables.
In the prior art, the use of rapid diagnostic tests (“RDTs”) may have been restricted and/or limited by inadequate, insufficient and/or lacking quality control (“QC”) and/or QC improvement.
RDTs may be sensitive to and/or affected by temperature, pre-analytical steps, reading errors, and/or storage problems. Most of these parameters may have never been addressed as a global issue, but managed only as separate issues.
What may be needed is a system, method, and/or computer readable medium which enables QC issues to be monitors and/or the overall improvement QC with respect to any RDT device, user and/or consumables.
As an aside, it is here noted that at least some portions of the present disclosure may apply equally well to non-RDT diagnostic tests, and the present invention and disclosures therefore will be appreciated by persons having ordinary skill in the art to extend to include and apply to such subject matter as well.
What may be needed is a system, method and/or computer readable medium which is operable by a service provider who (operating portions thereof for end users) may preferably have expertise in diagnostics, image processing, cellular communications, user interfaces, software development, nano- and polymer chemistry, optics, information science, industrial design, and/or database solutions. The service provider's clinical expertise may preferably include internal medicine and/or infectious disease clinical practice and/or research, diagnostics, regulatory affairs, and/or clinical trials.
Some of Today's Related Challenges
The World Health Organization (“WHO”) may recommend that all cases of presumptive malaria be confirmed with a diagnostic test, yet most fevers may not receive proper diagnosis before treatment. Health workers in malaria endemic regions may often assume that fever may be caused by malaria and/or may over-treat with anti-malarial medication. Misdiagnosis may increase morbidity and/or mortality. Overtreatment may increase the risk of drug resistance. Valuable and/or limited health resources may thus be wasted.
While the adoption of malaria RDTs may have improved fever management, impact may have been hindered by factors such as quality issues, human error and/or variation of interpretation, some or all of which may decrease accuracy and/or impact quality of care. The same factors may impair the real-world accuracy of non-malaria RDTs as well.
Infectious disease surveillance in developing countries may be compromised by inaccurate, incomplete and/or stale data, perhaps due to the current labour-intensive and/or error-prone manual capture and/or transcription of diagnostic results. This may impair the ability of program managers to make timely, data-driven resource allocation decisions, perhaps leading to inefficient use of current resources.

QC Analysis Subsystem
The QC analysis subsystem determines when the test QC data are outside the corresponding QC parameters. Preferably, the analysis subsystem generates a QC analysis report on whether the test QC data are outside the corresponding QC parameters.
In some preferred embodiments, the QC data subsystem identifies the corresponding QC parameters for authentic consumables. The analysis subsystem validates the consumables as authentic when the test QC data are within the QC parameters, and identifies the consumables as counterfeit when the test QC data are outside them.
QC Improvement Subsystem
When the test QC data are outside the corresponding QC parameters, the QC improvement subsystem generates QC improvement data associated with the test devices, users or consumables.
QC Database
The QC database receives and stores the QC improvement data for use in improved QC procedures associated with the test devices, users or consumables. Preferably, the QC database also receives and stores the QC analysis report.
i. Remote
In some preferred embodiments, the QC database is stored remotely from the test devices. The QC data subsystem, analysis subsystem, and improvement subsystem are preferably also located remotely from the test devices.
ii. Local
In these and other preferred embodiments, the QC database is stored onboard a local test device. The QC data subsystem preferably collects the test QC data from and associated with the local test device. In some such embodiments, the QC data subsystem, analysis subsystem and improvement subsystem are also preferably substantially local with the QC database and onboard the local test device.
iii. Peer-to-Peer
In these and other preferred embodiments, the QC data subsystem preferably collects the test QC data from and associated with a remote peer group of the test devices. Congruent copies of the QC database are preferably updated and stored onboard each of the test devices in the remote peer group.
Improvements
Preferably, the QC improvement data and the improved QC procedures are based on: the test QC data collected by the QC data subsystem; and/or statistic/algorithmic analyses performed by the QC analysis subsystem.
In some preferred embodiments, the QC data subsystem collects the test QC data, and identifies the corresponding QC parameters, with reference to two or more patient identification images of the consumables. The QC analysis subsystem registers the images against one another based on an affine transformation. In these and other preferred embodiments, the QC improvement data or the improved QC procedures may require the images of the consumables to be registered against one another based on an affine transformation.
Preferably, the QC improvement data and the improved QC procedures may: require training and certification of selected users; provide for set-up and management of the test devices and consumables; provide for workflow images to be taken by the test devices at regular intervals; and/or provide a QC diagnostic application for use by the test devices.
QC Method
Persons skilled in the art will appreciate that although some of the components, relations, functionalities and applications of the system and computer readable medium are not specifically referenced or described in conjunction with the QC method, they may be used or adapted for use in association therewith.

Preferably, the QC system, method and computer readable medium provide types of QC improvement as follow:
Preferably, the QC system, method and computer readable medium may be used through a QC server. In this case, the data workflow and/or the applications may preferably be hosted by and/or inside a QC server. (See, for example,
Preferably, the QC system, method and computer readable medium may also, or instead, be used onboard and/or inside the test device. Alternately or in addition, the QC applications may preferably be hosted inside the test device. Updates of the QC databases and/or algorithms may preferably be done periodically, preferably based on user requirements and/or access to a network. (See, for example,
Preferably, the QC improvements are sent to the devices and the QC databases.
