What is a bone marrow biopsy?

A bone marrow biopsy is a diagnostic procedure where a small amount of bone marrow tissue and cells are taken from the iliac crest, which is part of the pelvic bone located near the buttocks. The sample is examined under a microscope to diagnose blood disorders and monitor the effectiveness of treatment.

Preparing for a bone marrow biopsy

Before the biopsy

1.
If you're at risk for bleeding due to a low platelet count, you may receive a platelet transfusion.
2.
Please use the restroom before the procedure.

During the biopsy

1.
You'll need to lie face down to keep still during the biopsy.
2.
Local anesthesia will be administered to minimize discomfort.

After the biopsy

1.
A sandbag may be placed over the biopsy site, and you should lie flat for 2-4 hours to promote clotting.
2.
If you experience significant pain or notice bleeding, inform the nursing staff immediately.
3.
To reduce the risk of infection, keep the biopsy site dry for the next 24 hours. Please avoid showering during this period.
4.
After showering, disinfect the biopsy site with alcohol or povidone-iodine. Apply a new bandage daily for the next 2-3 days. Once a scab has formed, further disinfection is usually not required.
5.
Should you notice any bleeding, redness, or pain at the site, contact the leukemia outpatient clinic or the bone marrow biopsy room immediately or go to the hospital.
