Clinical biochemistry laboratories support various aspects of healthcare, including routine blood tests, specialised investigations, and blood analysis for critical care monitoring. From each of these units, various tests are ordered with no consequence in diagnosis or decision-making. The proportion of repeat and redundant tests appears to be increasing in routine laboratory practice, compromising the quality and standards of laboratory work. Greater awareness among clinicians is needed regarding the time, effort, and resources wasted on unnecessary testing. The present review aimed to give an account of the impact of redundant tests on laboratory quality management. The articles available on PubMed and Google Scholar in the last ten years, that is, from 2014 onwards, on the impact of redundant laboratory tests were included in the present study. Strict inclusion and exclusion criteria were followed to induct the research material appropriate for the review. Care was taken to include quality research papers. A detailed analysis and comparative assessment of biochemical tests and their redundancy has been reported. Findings from various studies highlight that minimising repeat test requests can conserve laboratory and financial resources; however, repeat investigations are not always insignificant, particularly for critical values. Modern clinical laboratories offer a wide range of tests, enabling clinicians to select appropriate investigations at suitable intervals for patient care. Establishing standardised laboratory protocols in collaboration with clinicians can promote good laboratory practices within institutions.
