An overview of medical diagnostic laboratories in South Africa that meet the international standard of accreditation: ISO 15189

Accreditation is an official recognition that a facility or laboratory is competent to perform specific tasks and has a documented manual on a Quality Management System (QMS) in place. According to the Accreditation Act 19 of 2006, South African National Accreditation Systems (SANAS) is the only internationally recognised accreditation body in South Africa. The International Organization for Standardization (ISO) standard specifically for medical laboratory accreditation is ISO 15189:2012. This review is designed to bring awareness of accredited and unaccredited medical diagnostic laboratories in SA; to look at the number of accredited, unaccredited laboratories and the rate of accreditation growth; to examine the state of accreditation in South Africa with regard to how many are accredited, suspended or withdrawn; and to highlight the advantages of being an accredited laboratory. It also examines the nonconformances commonly raised during assessment and an overview of accreditation around the world. Upon accreditation, the laboratory is given the right to use the SANAS symbol on patient request forms or results as a confirmation of competency. This has motivated more and more laboratories to be accredited. Diagnostic laboratories contribute much toward the final decisions taken by clinicians to diagnose the patients or treatment; this may be from an accredited or non-accredited laboratory. Since patient care is inextricably linked to pathology testing, every laboratory should engage a premium QMS and be evaluated by an accreditation body to ensure that patients receive a trustworthy report. Accreditation is a voluntary process in South Africa but mandatory in some Western countries. Although some laboratories might lose accreditation along the way, the ratio compared to those accredited is still very small. The fact that a majority remain accredited is a good indication of a well-implemented QMS. The challenges faced by the medical technologist-owned laboratories remain, as they are still not accredited.
