Which practice best supports optimizing turnaround time (TAT) in a drug testing lab?

• A. Defining milestones after the run completes.
• B. Defining milestones, monitoring sample flow, identifying bottlenecks, and applying automation or scheduling strategies.
• C. Increasing sample volume without process review.
• D. Relying solely on manual processes.

Answer: (B)

Efficient turnaround time comes from proactive end-to-end workflow management rather than waiting for a run to finish. By defining milestones throughout the process—from receipt, accessioning, and preparation, through analysis and review to final release—you create clear checkpoints that show progress and reveal when a step is slipping. Monitoring sample flow in real time lets you see where samples pile up and which stage is driving delays. Identifying bottlenecks lets you target the slowest part—whether instrument throughput, manual prep, or data processing—and apply fixes. Applying automation or scheduling strategies then moves the flow faster: automating repetitive tasks, integrating instruments with the LIMS for seamless data transfer, and scheduling runs to balance resource use. This combination reduces TAT by preventing delays, speeding up adjustable steps, and making overall throughput more predictable. Defining milestones after the run provides no preemptive control, increasing volume without process review risks overloading the system, and relying only on manual processes slows everything and raises variability.
