ABSTRACT:
Systems and methods configured to guide and manage laboratory analytical process control operations. A Biometric quality control (QC) process application is configured to monitor bias and imprecision for each test, characterize patient population data distributions and compare, contrast, and correlate changes in patient data distributions to any change in QC data populations. The Biometric QC process monitors the analytical process using data collected from repetitive testing of quality control materials and patient data (test results). The QC process identifies the optimal combination of, for example, frequency of QC testing, number of QCs tested, and QC rules applied in order to minimize the expected number of unacceptable patient results produced due to any out-of-control error condition that might occur.
