I wanted to educate about why a Bone Marrow is needed in diagnosing the reason of abnormal complete blood count results. The Bone Marrow is the spongy tissue that is inside some of your larger bones such as iliai crest which is the on the side of hip area. Cells are produced in the bone marrow and should have normal amounts. If you have leukemia then there will be abnormal amount of cells.
In order to diagnose your medical condition the oncologist must do a Bone Marrow aspirate. Inside your bone is a fluid portion and a solid portion and this needs to be aspirated with a larger needle.

If your diagnosis is a blood cancer then you may have other bone marrow biopsies to see if your treatment is succeeding . Your bone marrow will be put into several tubes and the core(bone part) will be put in formalin.
The will perform genetic testing, flow cytometry , histology and stains.
Complications to bone marrows are rare. I would not take any aspirin and always make the doctor aware if you are taking any blood thinners.
