In order to receive CAP accreditation, a laboratory must demonstrate that it operates with the highest standards of quality, accuracy and consistency. The CAP inspection process investigates several components of the laboratory: assay validation data, quality management program, sample tracking procedures, lab personnel qualifications, facilities, safety, and having a lab that is compliant and ready for inspection. The CAP Laboratory Accreditation Process is an internationally recognized program designed to help clinical labs achieve excellence beyond that which is required for regulatory compliance.
