UKAS Accreditation and Tests

UKAS accreditation


This symbol shows that our laboratories have passed full accreditation against ISO standard 15189:2012.

Laboratories based at the John Radcliffe Hospital under registration number 8415 and the specialised bone laboratory based at the Nuffield Orthopaedic Centre under registration number 8683.

Accreditation provides formal recognition that the Cellular Pathology Clinical Services Unit [CSU] at OUH is competent to perform Cytology, Histology and Post Mortem services [which are detailed in the scope of accreditation] in a reliable, credible and accurate manner.

The CSU undergoes inspection for conformance with internationally recognised standards of ISO15189:2012 [medical laboratory accrediation].

As an accredited service our users can have confidence in the quality of the results, their traceability, comparability, validity and commutability.

For more information on accreditation to ISO15189:2012, the process and benefits it brings, please see:

'Non-accredited' tests

As a dynamic department, that continually seeks to improve for the benefits of patients, there are a number of tests and processes that are being developed or amended between accreditation visits.

Until they have been ratified by the UKAS team, it must be made clear that these new/amended tests/processes are not accredited by UKAS.

To ensure that tests are introduced in a safe way, with sound, scientific reasoning, the department follows prescribed procedures of acceptance testing, validation and verification of any new, or amended process.
