Understanding Bone Marrow Tests: Purpose and Procedure

A bone marrow test is a medical procedure used to examine the cells within your bone marrow, the spongy tissue inside your bones responsible for producing blood cells. This diagnostic tool is crucial for identifying potential cancer cells in the bone marrow or assessing the effectiveness of ongoing treatments.

Why Are Bone Marrow Tests Performed?

Bone marrow tests are primarily conducted for cancers that are likely to affect the bone marrow, including:

  • Lymphomas
  • Leukemias
  • Myelomas

However, these tests can be performed for any type of cancer if your doctor suspects bone marrow involvement or needs to rule it out. The test results can provide valuable insights into the presence of cancer cells and help monitor treatment progress.

Types of Bone Marrow Tests: Aspiration and Trephine Biopsy

There are two main types of bone marrow tests, often performed together to provide comprehensive information:

  1. Bone Marrow Aspiration: This procedure involves drawing liquid bone marrow into a syringe using a thin needle.
  2. Bone Marrow Trephine Biopsy: In this test, a small core of bone marrow (1-2cm long) is removed in one piece.

While both tests offer similar information, they differ in the aspects of bone marrow they examine. The aspiration focuses on the bone marrow cells, while the trephine biopsy provides insights into the structure of the bone marrow within the bone.

The Bone Marrow Test Procedure: Step-by-Step

Understanding what happens during a bone marrow test can help alleviate anxiety and prepare you for the procedure. Here’s a detailed breakdown of the process:

  1. Informed Consent: Your doctor will explain the procedure and ask you to sign a consent form. This is an excellent opportunity to ask any questions you may have.
  2. Preparation: You may be asked to change into a hospital gown, though you can usually keep your underwear on.
  3. Positioning: You’ll lie on your side with your knees tucked up to your chest.
  4. Sterilization: The area where the biopsy will be performed is cleaned with antiseptic fluid.
  5. Local Anesthesia: A local anesthetic is injected to numb the area.
  6. Aspiration: A thin needle is inserted through the skin into the hip bone to draw out a small amount of liquid bone marrow.
  7. Trephine Biopsy: If you’re having a trephine biopsy, a second needle is inserted to remove a small piece of bone marrow.

The entire procedure typically takes around 30 minutes to complete.

Potential Side Effects and Recovery

While bone marrow tests are generally safe, there are some potential side effects to be aware of:

  • Bruising
  • Bleeding
  • Pain at the biopsy site
  • Infection (rare)
  • Tingling in the legs

Most patients recover quickly from the procedure, with any discomfort subsiding within a few days. Your healthcare provider will give you specific instructions for post-procedure care and when to seek medical attention if needed.

Preparing for Your Bone Marrow Test

Proper preparation can help ensure a smooth and successful bone marrow test. Here are some steps you can take:

  • Inform your doctor about any medications you’re taking, especially blood thinners.
  • Discuss any allergies or previous reactions to anesthesia.
  • Arrange for someone to drive you home after the procedure, especially if you’ll be receiving sedation.
  • Wear comfortable, loose-fitting clothing to the appointment.
  • Follow any fasting instructions provided by your healthcare team.

By following these guidelines, you can help ensure that your bone marrow test goes as smoothly as possible.

Understanding Your Bone Marrow Test Results

After your bone marrow test, the samples are sent to a laboratory for analysis. The results typically become available within 1-2 weeks. Your doctor will review the findings with you and explain what they mean for your diagnosis or treatment plan.

What Can Bone Marrow Test Results Reveal?

Bone marrow test results can provide valuable information about various aspects of your health, including:

  • The presence or absence of cancer cells in the bone marrow
  • The stage of a known cancer
  • The effectiveness of cancer treatments
  • Blood cell production abnormalities
  • The cause of unexplained anemia or other blood disorders

It’s important to remember that while bone marrow test results can be crucial in diagnosing and managing various conditions, they are often used in conjunction with other diagnostic tools and clinical information to provide a comprehensive picture of your health.

Alternatives to Bone Marrow Tests

While bone marrow tests provide unique and valuable information, there are some alternative diagnostic procedures that may be considered in certain situations:

  • Blood Tests: Comprehensive blood panels can provide insights into blood cell counts and potential abnormalities.
  • Imaging Studies: CT scans, MRIs, or PET scans may be used to visualize bone marrow and detect abnormalities.
  • Flow Cytometry: This technique can analyze cells from blood or bone marrow samples to identify specific cell types and characteristics.
  • Genetic Testing: Advanced genetic tests can detect mutations associated with certain blood disorders or cancers.

Your healthcare provider will determine the most appropriate diagnostic approach based on your specific symptoms, medical history, and suspected conditions.

Advances in Bone Marrow Testing Technology

The field of bone marrow testing is continually evolving, with new technologies and techniques emerging to improve accuracy, reduce discomfort, and provide more detailed information. Some recent advancements include:

Minimally Invasive Techniques

Researchers are developing less invasive methods for obtaining bone marrow samples, potentially reducing patient discomfort and recovery time. These may include:

  • Fine-needle aspiration techniques
  • Image-guided biopsies for increased precision
  • Liquid biopsies that analyze circulating tumor cells or cell-free DNA in the blood

Advanced Analytical Methods

New technologies are enhancing the analysis of bone marrow samples, providing more detailed and accurate results:

  • Next-generation sequencing for comprehensive genetic profiling
  • Single-cell analysis techniques to study individual cells within the bone marrow
  • Artificial intelligence and machine learning algorithms to assist in interpreting test results

These advancements hold the promise of more personalized and effective treatments based on the unique characteristics of each patient’s bone marrow cells.

Living with a Bone Marrow Disorder: Coping Strategies and Support

If your bone marrow test reveals a disorder or malignancy, it’s important to remember that support is available. Coping with a bone marrow condition can be challenging, but there are strategies to help you navigate this journey:

Educate Yourself

Understanding your condition can help you feel more in control. Ask your healthcare team for reliable resources and information about your specific diagnosis.

Seek Emotional Support

Consider joining support groups or speaking with a mental health professional. Connecting with others who have similar experiences can be invaluable.

Maintain a Healthy Lifestyle

Focus on nutrition, exercise (as approved by your doctor), and stress management to support your overall health and well-being.

Communicate with Your Healthcare Team

Keep open lines of communication with your doctors and nurses. Don’t hesitate to ask questions or express concerns about your treatment or symptoms.

Plan for the Future

While dealing with a bone marrow disorder, it’s important to consider practical matters such as financial planning, work accommodations, and long-term care needs.

Remember, many people with bone marrow disorders lead full and productive lives with proper treatment and support. Your healthcare team is there to guide you through your treatment journey and help you maintain the best possible quality of life.

What is a bone marrow test?

A bone marrow test is a way of testing cells from your bone marrow. Bone marrow is the spongy tissue inside your bones that makes blood cells.

Why do I need it?

To find out whether there are any cancer cells in the bone marrow. You might also have one to check whether treatment is working.

How do you have it and how long does it take?

You have a local anaesthetic injection to numb a small area on your hip. The doctor puts a needle into your hip to suck out some bone marrow. The test takes about 30 minutes. You should get your results within 1 or 2 weeks.

Are there any side effects?

Possible side effects can include bruising, bleeding, pain, infection or tingling in the legs.

You have a bone marrow test to check whether there are cancer cells in your bone marrow. Bone marrow is spongy tissue and fluid that is inside your bones. It makes your blood cells. Depending on your cancer type, this test can also check how well your treatment is working. 

A doctor or specialist nurse removes a sample of bone marrow cells or an area of bone marrow in one piece. This is usually from your hip. A specialist doctor can then look at the cells or tissue under a microscope.

You usually have the test in the outpatient department of the hospital. But you may have this on the ward if you are staying overnight in hospital (inpatient).

You’re usually awake for the test. You have a local anaesthetic to numb the area. Some people have medicine to make them drowsy (sedation).

Why might you have a bone marrow test?

Bone marrow tests are usually done for cancers that are most likely to affect the bone marrow, such as:

  • lymphomas
  • leukaemia’s
  • myeloma

But it can be done for any type of cancer. This is usually if your doctor thinks your bone marrow could contain cancer cells, or they need to rule this out for any reason.

Types of biopsy

There are 2 main types of bone marrow test: 

  • bone marrow aspiration
  • bone marrow trephine biopsy

Aspiration means the doctor or nurse draws some liquid bone marrow up into a syringe.

A bone marrow trephine biopsy means they remove a very thin 1 or 2cm long core of bone marrow in one piece.

You usually have both of these tests done at the same time. They give some of the same information to the doctor, but there are differences. The bone marrow trephine shows the structure of the bone marrow inside the bone, whereas the aspiration takes just the bone marrow cells.

What happens

Your doctor will give you information about the procedure and asks you to sign a consent form. This is a good time to ask any questions you have.

You might need to change into a hospital gown. You can usually keep your underwear on.

You lie on your side with your knees tucked up into your chest.

Your doctor or nurse cleans the area with some antiseptic fluid. This can feel cold.

You’ll then have an injection into the skin over the biopsy site (local anaesthetic) to numb the area. They then put a thin needle through the skin into the hip bone. This might be uncomfortable for some, but this only lasts a short time.

Your doctor or nurse draws a small amount of liquid bone marrow into the needle, using a syringe. You might feel a pulling sensation when they start drawing the bone marrow cells out. 

They take this needle out and put the second one in if you are having a trephine biopsy. The aim is to get a small amount of marrow out in one piece.

The whole test takes around 30 minutes.

Take a look at this 2 minute video about having a bone marrow test.

What to expect when you have a bone marrow test

Your bone marrow is the spongy substance in the centre of the bones where the blood cells are made.

You may have a bone marrow test if you have a cancer which affects the bone marrow such as leukaemia, lymphoma or myeloma. if your doctor thinks your bone marrow may contain cancer cells that have spread from another type of cancer or you have a non-cancerous condition.

There are two types of tests. A bone marrow aspiration which takes some bone marrow cells and a bone marrow biopsy which takes samples of the bone marrow and gives more information about its structure.

Usually your doctor takes the sample from the back of your hip bone but you can have a bone marrow aspiration from your breast bone.

You have the test lying on a couch. You may have a sedative beforehand to make you sleepy. The doctor then injects some local anaesthetic to numb the area.

For a bone marrow aspiration they put a needle through your skin and into your bone. Then using a syringe they draw out some liquid bone marrow. You may feel a pulling sensation as they do this.

For a biopsy your doctor uses a slightly bigger needle to take the sample of bone marrow. They turn and push this needle to get the sample. This can be painful as the needle goes in but it doesn’t last for long.

You usually go home about half an hour after the test. If you had sedation you need to wait until you are fully awake. This can take a few hours.

Afterwards your hip will ache for a few days. Taking painkillers helps.

You may also have some bruising. Rarely you may have some slight bleeding from the site. Press on it if you do and if it doesn’t stop contact the hospital.

There is a small risk of infection. Tell your doctor if you have a temperature or the biopsy area becomes red and sore.

You may have some tingling in your leg which will also wear off with time.

Sedation

Some people prefer to have some type of sedative before the test so that they are a bit drowsy. Some hospitals may use gas and air (Entonox) to help relax you instead of sedation.

Children and teenagers often have sedation for this type of test.

We have a children’s cancer section where you can find out about this test if your child has acute lymphoblastic leukaemia (ALL).  

After your bone marrow test

You usually go home the same day if you’re feeling well enough.

You have a dressing over the site, which you should keep on for 24 hours. If you notice any bleeding apply pressure to the area. If it doesn’t stop, contact the hospital.

After the test, your hip might ache for a couple of days. You may need some mild painkillers such as paracetamol to take at home.

As you’re having sedation you’ll need someone with you so they can take you home and stay with you overnight. Also for 24 hours after you shouldn’t drive, drink alcohol, operate heavy machinery or sign any legally binding documents.

Possible risks from having a bone marrow test

A bone marrow test is very safe and any risks are small. 

During the procedure there is a very small risk of damage to nearby structures, but this is very rare.  

Bleeding

It’s not unusual to have a small amount of bleeding from the area where the needle went in. If you notice any heavy bleeding, apply pressure to the area. If it doesn’t stop, contact the hospital.

Bruising

Sometimes blood leaks out of the vein and collects under your skin. This can look like a small dark swelling under the skin (haematoma). Pressing hard once the needle is removed can help.

Infection

There is a small risk of getting an infection in the wound. Tell your doctor if you have a temperature or if the area becomes red and sore. 

Pain

Some people feel uncomfortable and have pain after the local anaesthetic has worn off. Your nurse will tell you what painkillers to take. If you have severe pain or it’s getting worse then you should contact the hospital.

Tingling in your leg

You may have some tingling in your leg which wears off with time.

Getting your results

Your bone marrow test is looked at in the laboratory. The time it takes to receive results depends on the which tests are being done on the bone marrow samples.

Basic results can be available as soon as 24 to 48 hours. Whereas if for example you’re having genetic tests on your bone marrow samples, these results can take a couple of weeks. You won’t get any results at the time of having a bone marrow taken. It’s best to ask your doctor or nurse how long it will take to get them.

Waiting for test results can make you anxious. You might have the contact details of a specialist nurse. You can contact them for information and support if you need to. It may also help to talk to a close friend or relative about how you feel. 

For support and information, you can call the Cancer Research UK nurses on freephone 0808 800 4040. The lines are open from 9am to 5pm, Monday to Friday.
