1. PURPOSE AND SCOPE This document describes how Bone Marrow Samples are processed in the laboratory and provides an overview of the diagnostic pathways used. It contains information for how to contact the laboratory and for how to handle out-of hours sample requests. The purpose of this document is for new clinical and science staff to quickly become familiarised with the procedure – it is not intended to provide a full account on how to carry out the procedure. 2.

3. PROCEDURE Introduction The aim is to produce an integrated Bone Marrow Report incorporating all the diagnostic techniques of aspirate cytology, bone marrow histology, flow cytometry, cytogenetics and molecular diagnostics. This is done in accordance with the 2012 NICE-IOG guidelines (gateway number 17241). This will only apply to Adult Bone Marrow Samples. An overview of the bone marrow diagnostic pathway is included in Appendix 1. Sources of Bone marrow samples
1- UHB Trust 2- Weston Super-Mare 3- Ad hock samples from other trust 4- Pre transplant samples for review- From various locations, predominately the
South-west. Requesting Bone Marrow samples The bone marrow investigations (slides/aspirate, flow, molecular, cytogenetics, trephine and iron stains) are requested on ICE by clinicians. The samples (slides/aspirate, EDTA samples for flow and molecular analysis, cytogenetics sample in heparin or transport media, and trephine pot) must be sent as one single package together with a print-out of the ICE request form. Every case needs to be sent immediately to the HODS reception (BRI main building, Pathology, level 8) for booking in and processing as soon as possible. All samples should be kept at room temperature.

Booking in
Every case will be booked in on Cellpath by laboratory staff in the SI-HMDS reception and thereby given a unique single identifying number. This includes all samples from referral centres. Labels with patient’s name and case request number will be attached to the request form and to all individual specimens.
The request form will indicate which samples have been taken: Slides/aspirate, flow, molecular diagnostics, cytogenetic, trephine and/or trial samples. Unlabelled specimens will not be processed. If samples have been requested but not received, SI-HMDS reception staff will note this on the request form and immunophenotyping report form. The originating clinic or SpR on laboratory rotation will be contacted to ensure that no sample has been lost in transport.
Iron stains are requested by duty haematologist after slide/aspirate interpretation. The request for iron stain is made on the Iron stain request sheet in the flow cytometry laboratory (LF-FLOW-Iron stain record, located on the white board next to the flow lab reception desk). Bone Marrow Trephine
The trephine biopsy will be sent immediately to Histopathology, level 9, for processing. Methods are all documented on Q-pulse and can be found by a search for “HIS” documents. The panels and antisera used are listed in appendix 2. Bone Marrow Slides/Aspirate
The slides, including any iron stains requested, are stained in the laboratory and taken into the morphology room for interpretation by haematologist. Specimen from referral centres may have slides analysed locally however, all slides are reported independently by UHB HODS as part of the integrated bone marrow report. Flow Cytometry
The samples need to be processed and analysed within 24 to 48 hours for optimum results. Samples arriving after 15.30 Monday–Thursday will be processed the following morning; If a sample arrives after 15.30 on a Friday it will be processed on Monday morning. Methods are all documented on Q-pulse and can be found by a search for “FLOW” documents. Tests offered are attached in appendix 3. Molecular Diagnostics
The relevant samples identified by SI-HMDS staff are analysed immediately. The RNA based assays need urgent processing for extraction of RNA. The molecular tests currently offered are attached in appendix 4. Methods are all documented on Q-pulse and can be found by a search for “MOL” documents. All bone marrow specimens are stored at +4oC for 3-4 months to make possible subsequent DNA analysis. Therefore requests for further DNA based molecular tests can be done at a later stage by the team. Should this be required, tests are requested by direct contact with SI-HMDS staff. Reflex tests form flow to molecular section are requested on internal request forms (LF-SI-HMDS-Int Mol Req), sample and form are handed directly to molecular staff or placed in the molecular sample fridge (room 60 fridge).

Cytogenetics All samples requiring cytogenetics testing should be dealt with immediately for best results. These samples will be forwarded to Bristol Genetics Lab, Cytogenetics, Southmead Hospital, by HODS staff. Tests offered are karyotyping, and FISH for the most common and relevant SI-HMDS related abnormalities. A complete list of tests offered is awaited form the cytogentics lab at the time of writing this document. Transports leave at 0900 or 1400hrs every week day. If necessary samples can be stored at 4oC over night. Urgent Samples arriving after 1400hrs on a Friday will need a courier (arranged by HODS staff). Samples stored by CG lab that requires to be analysed can be activated for analysis by contacting the laboratory by email: [email protected]. Trial Samples Trial samples are booked in on ICE request and forwarded to the relevant trial centre / laboratory via the BHOC Trials Unit. Trials staff must be informed in advance of the procedure to allow collection and transport arrangements for the trial sample. After Hours Monday –Thursday If a sample arrives after 5pm on Monday–Thursday it will be dealt with the following morning. Samples will be left at room temperature and send to level 8 in the SI-HMDS reception After Hours Friday and Weekends If a sample arrives after 5pm on a Friday or at a Weekend, it will be dealt with on Monday morning. Urgent samples For all such samples the SI-HMDS reception should be informed and appropriate members of SI-HMDS team contacted SI-HMDS reception: 0117 342 2596 Flow – Ulrika Johansson extension 22596 Histology – Dr Joya Pawade extension 22869 Molecular – Tim Clench extension 22596
