Final answer:
Faster turnaround time for results is a key advantage of using a physician's office laboratory, which leads to timely diagnosis and treatment as well as more efficient patient care.
Step-by-step explanation:
One advantage of completing laboratory tests in a physician's office laboratory (POL) is that the turnaround time is faster for finding out results. This expedited feedback allows for timely diagnosis and treatment, which can be critical for patient care. Compared to sending samples to an external lab and awaiting results, in-house testing avoids potential delays from transport and processing in busy labs. It enables healthcare providers to have quicker access to important diagnostic information and fosters efficient patient management.
