Turnaround times for samples

In May 2021, the Department of Clinical Neuropathology became part of an NHS/industry joint venture. The laboratory operations are now under the management of Synnovis LLP (a partnership between Guy’s and St Thomas’ and King’s College Hospital NHS Foundation Trusts, and SYNLAB UK & Ireland).

Timings listed are for an ‘average’ case. Cases that are difficult to diagnose will take longer, as more tests will be needed.
