BMT Scheme

Bone Marrow Trephine Scheme

The Bone Marrow Trephine (BMT) Scheme assesses archival bone marrow trephine specimens stained with haematoxylin & eosin and reticulin demonstration methods. 

Staining Criteria Handbook available in Members' Area

No. of assessment runs: 

6 distributions over a 12 month period 


Stains assessed:

Selected / In-house Material (all runs)  

Haematoxylin and Eosin (H&E) 

Reticulin (silver method for) 

Optional Romanowsky



A preparation technique is not specified, and the laboratory / organisation are free to use any suitable technique to adequately demonstrate the staining method.

BMT biopsies are carried out in a number of specialist and routine pathology centres and departments in the UK and overseas. 


They are an essential diagnostic tool to enable pathologists to diagnose an array of haematopathological disorders. 


As BMT is a specialised tissue, it is approached as such within routine laboratories, employing specialist handling. Best practice and close liaison with haematologists allows ease of reporting to ensure correct diagnosis.
