The clinical utility of a diagnostic test refers to its usefulness in improving patient outcomes, informing clinical decision-making, and optimizing healthcare resources. A diagnostic test with high clinical utility provides accurate, reliable, and actionable information that can guide appropriate treatment decisions, monitor treatment response, and identify potential adverse events or complications. Ultimately, the clinical utility of a diagnostic test depends on how well it can improve patient outcomes by guiding appropriate treatment decisions, improving clinical outcomes, and optimizing healthcare resource utilization. Healthcare providers need to weigh the benefits and drawbacks of using a particular diagnostic test in their clinical practice to determine its clinical utility.
