Clinical laboratories endeavor to secure quality by establishing effective quality management systems.However, laboratory environments are complex, and single quality control procedures may inadequately detect many errors.Patient-based real-time quality control (PBRTQC) is a laboratory tool that monitors the testing process using algorithms such as Bull's algorithm and several variables, such as average of normal, moving median, moving average, and exponentially weighted moving average.PBRTQC has many advantages over conventional quality control, including low cost, commutability, continuous real-time performance monitoring, and sensitivity to pre-analytical errors.However, PBRTQC is not easily implemented as it requires statistical algorithm selection, the design of appropriate rules and protocols, and performance verification.This review describes the basic concepts, methods, and procedures of PBRTQC and presents guidelines for implementing a patient-based quality management system.Furthermore, we propose the combined use of PBRTQC when the performance of internal quality control is limited.However, clinical evaluations were not conducted during this review, and thus, future evaluation is required.
