It may aid in the diagnosis of low numbers of red blood cells (anemia), low numbers of white blood cells (leukopenia), or low numbers of platelets (thrombocytopenia), or a high number of these types of blood cells. * The doctor can also determine the cause of some infections, diagnose tumors, determine how far a disease, such as lymphoma, has progressed, and evaluate the effectiveness of chemotherapy or other bone marrow active drugs. * Where the procedure is performed: Bone marrow aspirations and biopsies can be performed in doctor's offices, outpatient clinics, and hospitals. The procedure itself takes 10 to 20 minutes. Bone Marrow Biopsy Preparation
