What is the fourth and final step in Bone Marrow Inspection
Maturation of erythroid and myeloid series: In normal bone marrow 80% of the nucleated series should be rubricytes and metarubricytes. In the myeloid series, 80% of cells should be metamyelocytes, bands, and segmented Neutrophils. Blast cells should be less than 5% of the neutrophils. Blast cells should be less than 5 % of the total. If the greater than 30% of cells are blasts cells, a hemic neoplasia (ie. leukemia) is probably present.
