which do not set a particular level of quality or competence to be achieved
(see Section 11.7). There are also schemes of laboratory accreditation
more concerned with the quality of performance in specific tests. In the
UK this accreditation is usually sought through the UK Accreditation
Service (UKAS) which accredits laboratories over a whole range of
activities, not just microbiological testing. Most countries have their
own equivalent organization such as NATA (Australia), DANAK (Den-
mark), ILAB (Ireland) and STERLAB (The Netherlands). The accredit-
ing body inspects the laboratory and its procedures to ensure that tests
are carried out consistently and correctly using approved methods with
suitable quality control measures in place. Among the features investi-
gated are the training and qualifications of staff, the suitability of equip-
ment and procedures for its calibration and maintenance, participation in
a proficiency testing scheme and the presence of full documentation
prescribing the laboratory’s operating procedures.
Obtaining laboratory accreditation can be a costly exercise but, if
achieved, provides independent testimony to a laboratory’s proficiency
and will give increased confidence to potential customers.
