State-of-the-art Approach to Goal Setting.

Four external quality assurance programs combined their data to calculate the minimum acceptable quality specifications for laboratory testing. Other sources of quality specifications may be too stringent for the current market, or too lenient given the clinical demands on the test result, but these state-of-the-art goals may be practical and useful. Two main approaches were used: (1) defining the 95% percentile and comparing with other quality specifications, and (2) using an iterative approach to increase the quality specification until 90% of laboratories could achieve 75% of their results within the specification. 72 out of 82 analytes followed procedure 2.
