Fig. 2. Process of evaluating quality control (QC) results conducted at a testing site and central laboratory. Due to functional limitations of the point-of-care test (POCT) device, multi-rules for immediate evaluation at the testing site and central laboratory were separated. (A) At the testing site, if the QC data does not meet 12s or 13S, it is immediately repeated. If the results still do not meet 22s or R4s, it is determined that a systemic error has occurred with the device. (B) In the central laboratory, 41s was evaluated using the laboratory information system (LIS). The devices rejected by QC were submitted to the central laboratory, and the cause of the error was analyzed.
