The College of American Pathologists has surpassed 8,500 accredited laboratories worldwide, marking a new milestone for its Laboratory Accreditation Program.
CAP recently announced the milestone and said the program’s reach reflects laboratories’ continued use of accreditation as a framework for quality, risk reduction, and continuous improvement. The organization has operated the program for more than 50 years and uses inspections conducted by practicing laboratory professionals.
Accreditation connects standards with daily operations
Accreditation evaluates more than whether a laboratory has written policies. It examines whether the laboratory has the personnel, equipment, methods, quality controls, records, and management systems needed to perform testing within its accredited scope.
For lab managers, maintaining accreditation requires integrating those expectations into daily work. Equipment maintenance, staff competency, document control, method verification, corrective actions, and internal audits cannot function as isolated activities completed only before an inspection. They must operate as connected parts of the quality management system.
Peer-based inspections can also expose gaps that internal teams no longer notice because they have become familiar with existing workflows. External review can test whether the laboratory consistently follows its procedures and whether its records demonstrate that consistency.
CAP said its programs continue to evolve alongside changes in laboratory medicine, technology, and regulation. Although the announcement does not provide a year-over-year growth rate or a geographic breakdown for the accreditation milestone, it shows the scale of laboratories' use of a common external framework to demonstrate competence and quality.
Proficiency testing extends the quality picture
In addition to the accredited laboratories, CAP reported that it supports more than 23,000 laboratories worldwide through proficiency testing and external quality assessment programs, quality improvement resources, cancer protocols, and evidence-based guidelines.
Proficiency testing gives laboratories an external comparison of analytical performance. When results fall outside acceptance criteria, the value comes from investigating what happened, determining whether patient or customer results could be affected, and applying corrective action. Treating an unacceptable result as an isolated score can leave underlying problems in methods, training, equipment, or result review unresolved.
Laboratory managers considering accreditation need to evaluate which program and standard fit their testing, regulatory environment, customers, and business objectives. They must also account for inspection preparation, proficiency testing, staff time, documentation, corrective actions, and ongoing fees when planning resources.
For laboratories already accredited, CAP’s milestone provides a practical reminder that the certificate is not the endpoint. Accreditation depends on the laboratory’s ability to maintain control between inspections and demonstrate that quality practices remain active throughout the accreditation cycle.
