Bone marrow biopsy and aspiration

Prova diagnòstica d’anèmia

Bone marrow biopsy and aspiration are used to analyse marrow blood found in bone tissue and to diagnose blood diseases or other diseases involving bone marrow. Bone marrow is a diffuse organ that is present between the small cells of the bones and where the stem cells that give rise to the cells that circulate in the blood reside. Accessing this compartment of our bones therefore gives us information about blood precursor cells, and also whether invasive foreign cells or microorganisms are present.

Description

What is it used for?

This test is used to see all stages of blood cell maturity, both for diagnosis and to evaluate the response to treatment in neoplastic disease.

It is also used to rule out or confirm the presence of cells that should not normally be present.

 

How is it performed?

With local anaesthesia for spinal cord aspiration and under sedation for bone marrow biopsy. A puncture and aspiration of a bone area rich in precursor cells is performed.

Bone marrow aspiration can be done both in the sternum bone and in the iliac crest (back of the pelvis). A bone marrow biopsy can be performed in the iliac crest. A sample of bone tissue and marrow blood is taken from these areas through the puncture.

The procedure lasts between 10 and 15 minutes, after which the puncture site is strongly compressed for a few minutes and a dressing is applied, which must be removed after 24 hours.

It is necessary to bear in mind that, until 24 hours after the test has been conducted, no effort or weight should be put on that area. After this time, you can lead a normal life. In the event of pain or discomfort, pain killers can be taken.
