Turnaround times for main reports and additional tests

From 1 May 2021, the Department of Clinical Neuropathology has transferred to Viapath Analytics 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.
