What is Laboratory Accreditation?
Laboratory accreditation is a formal recognition that a testing laboratory is
competent to carry out specific types of tests and continue to satisfy all
the criteria set by approving bodies. It is regarded as a reassurance to
doctors and patients that the laboratory is performing to internationally
recognised ISO 15189 standards and requirements for medical testing. As
part of the laboratory accreditation process, Diagnostix Pathology
Laboratories have been inspected by independent teams of technical and
medical experts from two internationally recognised accreditation bodies, NATA
(National Association of Testing Authorities, Australia) and HKAS (Hong
Kong Accreditation Services).
What happens during accreditation assessment?
It is crucial that the laboratory is able to provide
accurate and reliable test reports on patient samples. This depends on the
fullfilment of the following:
• qualified and experienced staff;
• properly calibrated testing equipments;
• an adequate quality assurance system;
• proper sampling procedures;
• sound testing procedures;
• valid test methods;
• traceability of measurements to national and international
• accurate recording and reporting procedures;
• suitable testing facilities.
All these factors are checked during the accreditation
process to make sure that the laboratory is technically competent to do
What does accreditation means for the users of the
Accreditation by NATA or HKAS is A Recognition of
"NATA accreditation provides formal recognition
to competent testing facilities, thus providing a ready means for customers
to identify and select reliable testing, inspection, measurement and
calibration services. To maintain this recognition, laboratories are
re-evaluated periodically by NATA to ensure their continued compliance with
requirements, and to check that their standard of operation is being
maintained. The laboratory may also be required to participate in relevant
proficiency testing programs between reassessments, as a further
demonstration of technical competence. If a laboratory fails to
consistently meet all of NATA's requirements, their accreditation is
suspended or revoked."
What is ISO 9000?
Testing facilities may be checked and certified for
their compliance to international management system standards such as ISO
9000. Although this will give you confidence in the laboratory's management
system, it tells you nothing about its technical competence, or its ability
to provide reliable and accurate test data.
