The College of American Pathologists laboratory accreditation program

Abstract 

The College of American Pathologists (CAP) operates voluntary programs in proficiency testing (PT) and quality monitors, which are briefly described. Additionally, a peer-based laboratory accreditation program covers over 6,100 clinical laboratories. Participation requires successful PT and on-site inspections using a series of 18 checklists structured along traditional subdisciplines of laboratory medicine and anatomic pathology. The laboratory general checklist contains over 250 questions covering broad issues affecting all disciplines. Among these are three items within the computer services section that specifically probe the laboratory’s use of autoverification. Data autoverification is defined as the process by which the computer performs the initial verification of test results; any data that fall outside of set parameters should be reviewed by the human operator. Central to these questions is the role of the laboratory director in approving the rules and validation. CAP does not define the specific technical details, recognizing the uniqueness of each laboratory setting and the patients it serves.
