PRUH Reference Ranges

On 5 October 2023, Guy’s and St Thomas’ and King’s College Hospital NHS Foundation Trusts jointly introduced a new electronic health record (EHR) Epic and a new Laboratory Information Management System (LIMS) Beaker.

As a result, there have been changes to some reference ranges for our service users. Details of these changes can be found below.

*Please note: Reference ranges, changes and critical phoning limits on this page are for use from October 5 onwards.*

Biochemistry

These changes are relevant for clinicians at PRUH and for GP practices in Bromley.

Immunology

The following changes are applicable to clinicians at GSTT, KCH and primary care in south east London.
