For the clinical laboratory professionals who are only familiar with peripheral blood morphology, the first few observations of bone marrow aspirate smears can be overwhelming. These tests are used to examine bone marrow cells to find abnormalities, and are generally done at the same time. Check that the slide is properly stained. The difference in cellularity between the two sample types, not to mention the wider variety of cell types, can lead to mental and visual . Add oil and perform differential. Differential—determines whether cells in each lineage (WBC, RBC, platelet-producing cells) show orderly and complete maturation, and whether the cells are . Unless a systematic approach is followed, it may cause confusion in the differential diagnosis. It is very important to be able to recognize normal blood cells and to distinguish pathological cells from the normal variants. The presence of BME is an unspecific but sensitive sign of primary pathology and may act as a guide to . a Bone marrow cytology of normal cell density in a young adult (smear from a bone marrow spicule shown at the lower right; magnification X100). In my case, bone marrow smear differential's indicate that I'm low on myeloid precursors (early white cells) and high on early red cells, which matches a low M:E ratio.
