A computer-implemented method to process POC information for potential QC compliance issues. A system and method for implementation of traditional laboratory analyzer based QC compliance in point-of-care (POC) environments is disclosed. A specific system and method to analyze data from POC testing to identify when the testing exceeds the variation expected under stable operation (i.e., the testing is “out of control”) is disclosed. This system and method is characterized by solving the QC compliance problem for POC devices by individuals not trained in traditional laboratory practices. This also provides the capability in real-time or near real-time to analyze POC testing information regarding the performance of each POC device, reagent kit (i.e., one kit per analyte tested) and / or lot, and operator so one can respond quickly to a particular device, reagent kit and / or lot, or operator that is not performing properly.

The present invention details a nanostructured electrochemical biosensor based on aptamer as the molecular recognition probe. The biosensor is comprised of an electrochemical cell that can be plugged into an electric controller. This electrochemical biosensor contains a working electrode made of the micro- / nano-scale gold dot array pattern, on which aptamer is immobilized on the surface of the dot array as the molecular recognition probe. The aptamer is labeled with an electrochemical indicator. Reversible binding of an analyte to the aptamer causes the change in the conformation of aptamer, consequently brings the electrochemical indicator close to the electrode surface. This results in the electron transfer from the electrochemical indicator to the electrode, which can be read as a change in output current or potential. The invented biosensor is a portable point-of-care device that has higher sensitivity, allows the measurement of the analyte more rapidly and requires much less sample volume than is presently available with current methods of detection.
