Clinical Biochemistry Test and Platform Changes

From Monday November 14th 2022, we will be changing our test platforms in Pathology. The first department to go live with changes is Clinical Biochemistry, followed by other departments in the coming months.

Whilst the majority of reference ranges will stay the same, some are quite different. Specific protocols and reference range information is displayed below.

Summary of key changes to assays


Test accreditation

We are updating both our test information pages Test Information and the quality section Pathology Accreditation and Compliance Status with details of assays affected.

All the tests, which were previously accredited by UKAS, will be going under an Extension to Scope process. However, please be assured that the quality of our services will remain the same.


If you have any concerns or queries, please contact us (contact information in the box below).
