Evaluating Laboratory Performance With Quality Indicators

Show Summary Details



Quality indicators in the clinical laboratory provide a useful tool for continuous improvement of laboratory services. The goal of this study was to design and review quality indicators from time to time in an effort to improve the performance of the laboratory.


The study included an evaluation of different quality indicators collected from the biochemistry laboratory of a tertiary care hospital in New Delhi over a period of 1 year. A total of 84250 samples were processed, and the quality indicators monitored were classified into the following 3 categories: preanalytical, analytical, and post-analytical.


Hemolysis (0.7%) was the most common anomaly observed during the assessment of pre-analytical indicators followed by improper samples for coagulation profile (0.34%). In the analytical phase, the frequency for fibrin clots was 1.2%.


Working constantly to improve the outcome of these indicators by taking corrective measures over a period of time will definitely help to improve the quality of laboratory services and patient health care.
