What does the term "turnaround time" refer to in laboratory testing?

The term "turnaround time" in laboratory testing refers specifically to the period from the moment a specimen is collected until the results are reported. This encompasses all aspects of the testing process, including specimen handling, processing, and analysis, as well as the time taken for any necessary quality control measures and validation of findings.

Understanding this term is crucial in laboratory settings, as it helps determine the efficiency of laboratory operations and the overall responsiveness to patient needs. A shorter turnaround time is often associated with better clinical outcomes, as it allows for quicker decision-making regarding patient care.

Other factors such as specimen collection and the time taken to analyze specific samples relate to parts of the process that contribute to the overall turnaround time but do not encompass the complete duration represented by the term.
