Effective from 30/09/2026
CSF cytospin is an investigation for possible CNS malignancy, usually haematological, and should be paired with a sample for immunophenotyping. Testing is carried out at the regional HODS. On that basis local CSF cytospin testing is being discontinued. All cases should be discussed with a Haematology Consultant or Registrar upon request.
In the rare case where CSF analysis for non-haematological cancer is being considered the case should be discussed with a Consultant Oncologist as to whether CSF analysis is required and if so a Consultant Histopathologist for review
