How do I prepare for a bone marrow biopsy

Preparing for a Bone Marrow Biopsy

A bone marrow biopsy is a procedure where your doctor takes a small sample of bone marrow (the spongy tissue inside bones that produces blood cells) to examine under a microscope. Here's what you should know to prepare:

Before Your Appointment

Medications:

• Tell your doctor about ALL medications you take, especially blood thinners (like aspirin, warfarin, or apixaban)
• Ask specifically: "Should I stop any medications before my biopsy?"
• Don't stop medications on your own without approval

Lab Work:

• Your doctor may order blood tests beforehand to check your blood clotting ability
• This helps ensure you won't bleed excessively during the procedure

Fasting:

• Ask if you need to fast (not eat/drink) before your procedure
• This varies depending on whether you'll receive sedation

Clothing:

• Wear comfortable, loose-fitting clothes
• You'll need to expose the biopsy site (usually hip/pelvis area)
• Consider wearing pants you can easily pull down or a hospital gown

Day of the Procedure

What to Expect:

• The procedure typically takes 10-15 minutes
• You'll lie on your side or stomach
• The skin is cleaned and numbed with local anesthetic
• You may feel pressure and brief sharp pain when the needle enters the bone
• Most patients describe it as uncomfortable rather than severely painful

Bring:

• Insurance card and ID
• A list of current medications
• Someone to drive you home (if sedation is used)

After Your Biopsy

Recovery:

• You can usually go home the same day
• Avoid strenuous activity for 24-48 hours
• Take over-the-counter pain relievers if needed (ask your doctor which ones)
• The biopsy site may be sore for a few days

When to Contact Your Doctor:

• Excessive bleeding or oozing that won't stop
• Signs of infection (fever, increasing redness, warmth, or drainage)
• Severe pain not relieved by medication
• Swelling that worsens

Questions to Ask Your Care Team

1. Will I receive sedation or just local anesthesia?
2. How long will results take, and how will I receive them?
3. Are there any specific medications I should avoid before the procedure?
4. What should I do about pain management after the biopsy?
5. Are there any activity restrictions I should follow?

According to the American Cancer Society, bone marrow biopsies are important diagnostic tools for evaluating blood disorders and cancers. The National Comprehensive Cancer Network (NCCN) emphasizes that proper preparation and understanding the procedure helps reduce anxiety and ensures accurate results.
