🔬🦴🩸MYELOGRAM. HOW MANY CELLS TO COUNT? ✅Counting 500 cells is recommended in the 2008 and 2017 WHO classifications and the 2008 ICSH guidelines, especially for assessing potential myeloid neoplasia. ✅Counting 300 cells in a bone marrow aspirate smear yields results statistically similar to those obtained from counting 500 cells for a myelogram. Such conclusions were published in 2018 in the American Journal of Clinical Pathology (link below). ✅Reducing the number of cells counted can lead to decreased labor costs without compromising the quality of medical care.
