Metrics were based on data that are easily retrievable and calculable. Three key benchmarks were chosen for a pilot study: the ratio of 25-hydroxyvitamin D to 1,25-dihydroxyvitamin D test orders, the ratio of thyroid-stimulating hormone (TSH) to free thyroxine (FT4) test orders, and the percentage of iron workup orders after an initial low mean corpuscular volume (MCV).

A benchmark of 50:1 was established, where a higher ratio indicates intentional ordering of 1,25-dihydroxyvitamin D. Nine laboratories evaluated thyroid testing, with 3 implementing interventions. The benchmark of 3.5:1 was established, with a higher ratio suggesting judicious TSH ordering. Seven laboratories evaluated iron workups, proposing a benchmark of 50% as a starting metric. Intervention guidelines were provided for laboratories below the benchmarks to promote improvement.</p><p><strong>Conclusions: </strong>Benchmarking metrics provide a standardized framework for assessing and enhancing test utilization practices across multiple laboratories.
