Determination of Optimum Quality Control Testing Frequency for 27 Common Clinical Chemistry Analytes on Roche Cobas 702 Platform

AACC 2022 -- Quality Control (QC) testing frequency is based on a number of factors such as analytical stability, error tolerance without impacting results, testing volume, etc. Less than optimal frequency can result in erroneous results, which could lead to inappropriate clinical interventions. However, higher than optimum frequency can cause inefficiency in lab operations, put a strain on resources and negatively impact turnaround time (TAT) of reporting. Thus, an ideal balance of QC testing frequency needs to be evaluated and determined based on the aforementioned factors.
