Notification of change: Upgrade of analyser for Serum free light chains, Immunoglobulin subclasses and C1 inhibitor

In order to improve the service to our users we have upgraded the analyser used to run the following assays, Serum free light chains, Immunoglobulin subclasses and C1 esterase inhibitor. These were previously run on the Binding Site SPA analyser, which we have replaced with the Binding Site OPTILITE analyser, A full verification of the change has been performed. There are no changes to the reference ranges used for these analytes and the analysers both utilise the same methodology. However, these assays now lie outside our scope of accreditation as assessed by UKAS. UKAS have been informed and will assess the assays on the new analyser as an extension to scope of our accreditation at our next inspection in October 2018. This is normal procedure when changing analyser platforms.
