Bone Marrow Test: Procedure, Pain, Results & Recovery

Bone marrow tests are an important diagnostic process. It helps doctors to analyze the condition of bone marrow, the tissue that is present inside the bones responsible for producing blood cells. The doctor may advise the bone marrow test if the results of blood tests are abnormal that raise suspicions of any disease, infection, or cancer.
Bone marrow testing raises several questions in people’ minds particularly in terms of the procedure of the test, the kind of pain involved in the test, and the outcome. Knowing about the bone marrow test can be useful in such circumstances.

What Is a Bone Marrow Test?

Bone marrow testing helps in evaluating the bone marrow and its fluids. The test helps the doctor to understand how well is the bone marrow producing red blood cells, white blood cells, and platelets.

A bone marrow test generally consists of:

• Bone Marrow Aspiration: In which small amounts of liquid bone marrow are collected.
• Bone Marrow Biopsy: The procedure in which tiny pieces of solid tissue from bone marrow are removed.
• In many cases doctors do both procedures together to have a complete overview of the condition of the bone marrow.

When Is Bone Marrow Test Necessary?

Bone marrow tests are sometimes recommended by physicians in the following cases:

• A person has unexplained anemia
• A person has continuing fever of unknown origin
• There is an abnormality in white blood cell counts
• There are indications of leukemia
• There are signs of myeloma
• There are indications of some bone marrow diseases
• Iron levels must be tested, and it is essential to identify cases of excessive levels of iron and iron deficiency
• The efficacy of cancer treatment may need to be evaluated

A bone marrow test provides much-needed information that cannot be gathered through a normal test.

Bone Marrow Test Procedure: Step-by-Step

Many individuals ask themselves, "What is a bone marrow test?" The procedure itself takes roughly 20-30 minutes to perform and is classified as an outpatient procedure.

So, what happens during the procedure? 

• The patient lies on his/her side/stomach.
• The area is disinfected. 
• The local anesthetics are injected. 
• The needle penetrates the bone. 
• The first step is the extraction of the sample. 
• The bandage is applied and the bleeding is stopped. 

The procedure may appear overwhelming, but it will be performed accurately by a professional.

Is a Bone Marrow Test Painful?

Much of patient’s worry would stem from an anticipated pain associated with the bone marrow aspiration procedure. Luckily, local anesthesia can help ease the pain surrounding the skin. Yet, people could still face:

• The pressure while putting in the needle
• A sharp but brief pain occurring during aspiration
• Minor discomfort followed by the procedure
• Sore sensations afterward

Each person has different pain thresholds, but the pain is usually described to be somewhere in a range between mild and not lasting very long.

How long does it take usually for the pain to subside?

Most discomfort will be gone in:

• A day or two for minor discomfort
• A few days for complete recovery

Your healthcare provider may prescribe you over-the-counter medications, as long as they do not promote broader bleeding.

Bone Marrow Test Results: What They Mean

The time taken to receive results after undergoing the bone marrow is stressful. Results are reported after a certain number of days depending on the tests performed. In some cases, the tests done can take even weeks.
The results report shows: –

• The number of blood-forming cells and their appearance
• Presence of abnormal or cancer cells 
• Bone marrow cellularity 
• Presence of iron stores 
• Presence of signs of infection 
• Occurrence of fibrosis or scarring 
• Presence of some genetic abnormalities, when applicable.

What does a normal report indicate?

A normal report indicates: –

• Good production of blood cells in the body
• No signs of leukemia 
• Normal functioning of the bone marrow 

What do the abnormal results indicate?

Abnormal results may indicate: – Presence of leukemia – Presence of lymphoma – Presence of myeloma – Aplastic anemia – Presence of myelodysplastic syndromes – Development of bone marrow fibrosis – Spread of cancerous cells to the bone marrow – A few infections – Disorders in blood cell productions 
Though abnormal results do not always indicate the presence of cancer, the physician may use them for making diagnosis based on symptoms, laboratory tests and medical history of a patient.

Recovery After a Bone Marrow Test

Most individuals are back to normal within a short period of time after the procedure.
