Bone Marrow Biopsy
Bone Marrow Biopsy
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.
