Things worth knowing about "Bone Marrow Cell Analysis"

Bone marrow cell analysis is a diagnostic procedure in which cells are taken from the bone marrow and examined under a microscope. It helps detect blood disorders and tumors at an early stage.

What is Bone Marrow Cell Analysis?

Bone marrow cell analysis (also known as bone marrow cytology or myelogram) is a diagnostic procedure in which cells from the interior of bones – the bone marrow – are collected, processed, and examined under a microscope. Bone marrow is the blood-forming tissue of the body, located primarily inside flat bones such as the iliac crest (pelvic bone), the sternum (breastbone), and the femur (thigh bone).

By analyzing bone marrow cells, physicians can draw conclusions about blood cell production (hematopoiesis), the presence of abnormal cells, and a wide range of diseases affecting the blood-forming system.

When is Bone Marrow Cell Analysis Used?

This examination is typically ordered when changes in a complete blood count cannot be sufficiently explained, or when a serious underlying disease is suspected. Common indications include:

Suspected leukemia (blood cancer) or lymphoma
Unexplained anemia (low red blood cell count)
Thrombocytopenia (low platelet count) or thrombocytosis (elevated platelet count)
Suspected multiple myeloma
Staging (determining the spread) of cancers and lymphomas
Monitoring treatment response after chemotherapy or stem cell transplantation
Unexplained enlargement of the spleen or liver

How is Bone Marrow Cell Analysis Performed?

Bone Marrow Aspiration

The procedure begins with a bone marrow puncture. Under local anesthesia, a specialized needle is inserted into the bone – most commonly the posterior iliac crest (the back of the pelvic bone). Liquid bone marrow (aspirate) is then drawn out using a syringe in a process called bone marrow aspiration.

Bone Marrow Biopsy

In addition, a bone marrow biopsy (core biopsy) may be performed, in which a small cylindrical piece of bone and marrow tissue is removed. This allows a histological assessment of the bone marrow architecture – meaning the spatial arrangement of cells within the tissue.

Laboratory Analysis

The collected material is spread onto glass slides, stained, and evaluated microscopically. The analysis typically includes:

Differential cell count (myelogram): counting and assessing different cell types and their precursors
Cytochemistry: specific staining techniques to identify cell types
Immunophenotyping (flow cytometry): identification of surface markers on cells
Cytogenetics: chromosomal analysis to detect genetic abnormalities
Molecular genetics: detection of specific gene mutations or fusion genes

What Do the Results Mean?

A normal myelogram shows a balanced distribution of all cell lines – including red blood cell precursors, white blood cell precursors, and platelet precursors. Abnormalities may indicate various conditions, such as:

Hyperplasia or hypoplasia of individual cell lines (overproduction or underproduction)
Presence of blasts (immature, abnormal cells) in leukemia
Plasma cell proliferation in multiple myeloma
Aplasia of the bone marrow (severely reduced or absent blood cell production)
Infiltration by tumor cells or lymphoma cells

Risks and Side Effects

Bone marrow puncture is a safe procedure, but it does carry some risks. Possible complications include:

Pain during and after the procedure
Local bruising or bleeding at the puncture site
Rare risk of infection
Very rarely: injury to adjacent structures

The procedure typically takes only a few minutes and is performed on an outpatient basis. General anesthesia is usually not required.

Significance in Modern Medicine

Bone marrow cell analysis is an indispensable tool in hematology and oncology. It enables not only diagnosis but also precise classification of blood and bone marrow diseases according to international standards (e.g., the WHO Classification of Myeloid Neoplasms). This forms the basis for selecting the appropriate therapy and monitoring disease progression over time.
