ISO 17043 Accreditation for Proficiency Testing

The CAP is committed to providing the highest quality proficiency testing (PT) materials possible. As an accrediting organization, we recognize the value in having an independent assessment of our management system for our PT programs. That’s why the CAP is accredited by the ANSI National Accreditation Board (ANAB) to the international standard ISO 17043:2010 for PT.

Not only are our PT/External Quality Assessment (EQA) programs designed by experts in their field to help you verify the accuracy and reliability of your testing process, but you can also be confident that the programs we provide are of the highest quality. As medicine, technology, and pathology evolve, our comprehensive range of PT/EQA programs also continue to evolve, helping your laboratory to stay ahead of new technologies and rapidly changing testing requirements.

Our Quality Policy

  • To satisfy customer expectations;
  • To provide proficiency services of the highest level of professionalism and integrity, accredited or approved to those standards against which our quality management system has been established;
  • To implement and continually improve our quality management system and its effectiveness, consistent with this quality policy;
  • To ensure that all clients are treated equitably and impartially and that their confidentiality is maintained;
  • To consider market needs when developing new services;
  • To ensure that this quality policy is understood, implemented, and maintained at all levels within our organization.

The CAP's accrediting body, ANAB, accredits our PT/EQA at a program level. This robust accreditation requires an extensive review of all analytes in each program in scope.

As the largest PT provider to the clinical community, we will add disciplines to our scope of accreditation as the needs of the community dictate.

Testing Classes

Chemistry, including routine chemistry, drug monitoring, urine drug screen, lipids, enzymes, immunology, endocrinology, fecal occult blood, blood gases, oximetry, and glucose point-of-care testing

Hematology, including routine hematology, red cell disorders, coagulation, morphology, bone marrow, flow cytometry, and fetal maternal hemorrhage

Cytopathology, including gynecological and non-gynecological sample types

Microbiology, including bacteriology, C. difficile antigen and/or toxin detection, smears for acid-fast bacilli, C. trachomatis/N. gonorrhoeae by NAAT, mycology, parasitology, viral serology, and direct viral antigen tests

Pathology, including various immunohistochemical predictive or prognostic markers such CD117, Ki67, ER/PR breast tumor predictive markers, special stains and/or oversight stains (H&E or HPS)

Point-of-care testing (chemistry, glucose, urine drug screen, and HIV antibody)

Transfusion medicine, (ABO, Rh, antibody detection/identification, phenotype, DAT, titration, crossmatch), thus giving us the ability to offer ILC/PTs for numerous sub-disciplines. Please review the CAP’s scope to view all available sub disciplines.
