Use Of Process Capability Indices In Evaluating A Clinical Laboratory Chain's Quality Control Procedures

Abstract

To determine how useful the process capability indices C p and C pk are for evaluating chain laboratory facilities' quality control procedures. Total protein, albumin, and urea showed trueness individual improvement, precision individual improvement, and precision common improvement, respectively, when the process capability indices at the Jinan KingMed Center were compared to the standard values. The results of the other assays remained stable. Process capability indices can help increase the accuracy and validity of laboratory tests and are helpful in assessing the quality control protocols used in lab facilities.
