==Bone marrow biopsy==
Evaluate the following:
*'''Adequacy''': There should preferably be 5 intertrabecular spaces.
*'''Cellularity''': The percentage should be 100 minus age, such as 40% in a 60 year old patient.
*'''Thrombopoiesis''': There are normally about 3 megakaryocytes per 40x field.
*'''Myeloid/erythroid ratio''', normally 3-4 myeloid cells per erythroid cell.
*Look for any '''granuloma''' or '''cancer metastasis'''
