What does the term ‘turnaround time’ refer to in lab testing?

The term ‘turnaround time’ in lab testing specifically refers to the total time taken from when a test is ordered until the results are reported back. This includes every step in the process, starting from the moment a healthcare provider requests the test, moving through sample collection, processing, analysis, and finally to reporting the results. It is an important measure in laboratory operations as it reflects the efficiency of the testing process and impacts patient care.

In contrast, the other choices focus on narrower components of the laboratory workflow, such as transport time, consultation durations, and preparation of equipment. While those aspects may contribute to the overall turnaround time, they do not encapsulate the entire scope of what turnaround time represents. Thus, the correct answer comprehensively captures the full lifecycle of testing from request to result.
