Clinical Blood Sciences Analyser Transition and UKAS accreditation status

As part of the planned transformation of services within Clinical Blood Sciences, some tests that are now performed on our newly deployed analysers will be removed from our accreditation scope pending reassessment. This is standard procedure as required by UKAS, and the reaccreditation of these tests on the new analysers is already underway.

Please be assured that this is a normal and anticipated part of the transition process. The laboratories remain accredited for all other activities during this period, and our processes with the new analysers are in line with the requirements set out by ISO15189:2022. We are working closely with UKAS to complete the extension to scope process to return these tests to our accreditation scope as quickly and efficiently as possible.
