Re: lym19

The correct answer is D. The iliac bone is used most commonly for bone marrow biopsy. The sternum is a less common substitute site, which is used if iliac biopsy fails. The other sites are not usually used for bone marrow biopsies unless sampling of a radiologically demonstrated lesion is attempted.

Re: lym19 babbu5508 - 06-30-11 18:38 Abnormal results may be due to cancers of the bone marrow (leukemia or Hodgkin's disease).
The results may detect the cause of anemia (too few red blood cells), abnormal white blood cells, or thrombocytopenia (too few platelets).
