Turnaround Time Isn't Everything: Measuring What Really Matters in the Laboratory

For years, I've heard people say that the best laboratory is the one that delivers reports the fastest. While turnaround time is certainly important, I don't think it tells the whole story. As laboratory professionals, we are not simply in the business of producing reports quickly — we are in the business of helping clinicians make the right decisions. A report delivered an hour earlier has little value if it is inaccurate, incomplete, or fails to answer the clinical question.

In my three decades of experience, what clinicians remember is not just how fast a report arrived — it is whether they could trust it. Accuracy, consistency, clear communication, and dependable quality build confidence over time. I have seen laboratories with slightly longer turnaround times earn tremendous respect, simply because their results are reliable, their teams are approachable, and they work closely with clinicians to solve problems. Trust is built over years, not minutes.

I also believe we need to broaden the way we measure laboratory performance. Instead of focusing only on turnaround time dashboards, we should be asking bigger questions. Are we reducing diagnostic errors? Are clinicians satisfied with our service? Are we preventing unnecessary repeat testing? Are we genuinely improving patient care? These are the outcomes that define the true value of a laboratory. Numbers matter — but the impact behind those numbers matters far more.

As laboratory leaders, it is our responsibility to look beyond speed. Every sample belongs to a patient waiting for answers, and every report has the potential to change a life. The best laboratories do not simply aim to be the fastest — they aim to be the most trusted. When we combine quality, accuracy, teamwork, and genuine clinical partnership with reasonable turnaround times, we create something far more valuable than efficiency. We create confidence, better clinical decisions, and ultimately, better patient care.
