Does a haematology perform bone marrow biopsy?

The procedure may also be carried out by another specifically trained clinician within the haematology service, with samples assessed by a specialist laboratory.

Bone marrow is the soft tissue inside bones where blood cells develop. A clinician usually takes a liquid marrow sample and a small core of marrow tissue from the back of the pelvic bone. Local anaesthetic numbs the skin and tissues over the sampling area. You may still notice pressure or a brief pulling sensation while the samples are collected.

The samples can show the types and maturity of blood cells, the structure of the marrow and whether abnormal cells are present. Laboratory specialists may add tests tailored to the suspected condition. Results are interpreted alongside blood counts, symptoms, scans and previous treatment rather than in isolation.

Tell the team about blood-thinning medicines, bleeding problems, allergies and any infection near the proposed sampling area. Check whether you may eat and drink normally and whether sedation is planned; sedation can change transport and fasting instructions. Afterwards, keep the dressing and biopsy area managed as directed, avoid strenuous activity for the period advised and use only recommended pain relief.

Contact the haematology service promptly if bleeding continues despite firm pressure, pain is increasing instead of settling, or the site becomes more red, swollen, warm or starts draining fluid. Fever or chills after the procedure also need timely medical advice. Heavy bleeding, fainting, severe breathing difficulty or a serious reaction after medicines used for the procedure warrants emergency help.

Ask what the biopsy is intended to clarify, whether both liquid and core samples are planned, and what pain-control options are available. Confirm how to manage regular medicines, whether someone must accompany you, when the dressing can be removed and how results will be shared. If more laboratory testing may be needed, ask whether that could affect the timing of the final explanation.
