Understanding Your Diagnosis

  • Bone Marrow Biopsy

    In the center of most large bones there is a soft tissue called bone marrow. Bone marrow makes most of the body's blood cells. A bone marrow biopsy involves removing tissue from the red bone marrow. The tissue is sent to the lab for microscopic exam. The biopsy is done using a small needle inserted into the bone.

  • Lumbar Puncture

    A lumbar puncture (LP) or spinal tap may be done to diagnose or treat a condition.
