The department of HODS provide an integrated Haematopathology diagnostic service which covers Histopathology, Diagnostic Cytology, Immunophenotyping and Molecular pathology. A close collaboration with HODS ensures that information from all these modalities is integrated into the final report with an aim of reaching an accurate diagnosis.

We accept referrals of all types of diagnostic specimens (blood, bone marrow, formalin-fixed/fresh tissue samples, etc.) from NHS and private providers within the United Kingdom.

Specimen labelling:

  • The sample pot(s) must be labelled with the patient name, date of birth, and hospital number/NHS number, so an addressograph label is ideal.
  • Different samples must be distinguished by labelling the pots e.g. left or right. Any lack of information or mislabelling on the specimen pot(s) or form may result in the sample being returned to the sender causing a delay in processing the sample.

Specimen requirements

  • See table for further details.

Samples may be rejected or returned if :

  • Specimen or request form contains insufficient details to identify a patient
  • Blood samples are clotted
  • Liquid samples are in the wrong collection tube (e.g. serum/citrate)
  • Aged samples (for RNA based assays)  

Fresh or fresh-frozen tissues

  • Paraffin-embedded tissue-fixed in Bouin's, B-5, acids or fixatives other than neutro-buffered formalin
  • Paraffin block or section contains no or insufficient tissue
  • Paraffin block or section contains no tumour or insufficient tumour load to perform the requested assays
  • Specimens for analysis of acquired mutations must contain greater than 20% tumour cells in a whole section or in a macro-dissectible area

We will still issue a report if a sample is rejected.
