title: Interlaboratory survey of enzyme analyses: V. A simplified method of reporting participants' data.
abstract: The College of American Pathologists' Enzyme Survey continues to provide a valuable measure of the analytic quality of clinical enzymology for its participants and for the laboratory community. An updated reporting format for the participants simplifies the interpretation of Enzyme Survey data and should make it more valuable for detecting short- and long-term changes in accuracy and precision. A short-term CV of 3% and a long-term CV of 6% are recommended as analytic goals for the five enzymes described here. The upper limit of normal used by many laboratories is appropriate for a given enzyme yet remains as an area requiring urgent further study.
