RBH 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.*
