Significance of cellularity, myeloid to erythroid ratio, and quantitation of storage iron as used in bone marrow examination reports

on 7.3.09 with 0 comments



  • The volume of hematopoietic cells is expressed as a percentage, which can be roughly figured by [(100-age) +/- 10]%

  • The myeloid to erythroid ratio should normally be about 1.5-3:1

  • Storage iron (hemosiderin)

    • Stored in 30-40% of RBC precursors (called sideroblasts)

    • Present in macrophages
