For many years, the College of American Pathologists (CAP) has been developing a laboratory data base beyond comparison. The components include results of surveys of proficiency testing, quality-control and assurance data, laboratory inspection and accreditation results, and work load recording figures. Thousands of laboratories voluntarily have contributed results in order to measure, compare, and improve their quality. This book provides access for the first time to a statistical summary of this giant data base. It reports without editorial comment on millions of actual measurements in hematology, microbiology, immunohematology, immunology, and clinical chemistry. Through charts and graphs, it demonstrates the frequency distribution and coefficient of variation of 112 analytes. The data suggest that for many analytes the state of practice of medical laboratory analysis in the United States requires no more improvement, while pointing out other analyses for which practical improvements are desirable.
