Full Myelogram Assessments

• Manual slide evaluation. 
• Performed under oil immersion by counting a minimum of 500 intact nucleated myeloid, erythroid, and lymphoid cells. 
• Any notable abnormalities of the sample and evaluated cell lines are recorded, megakaryocytes numbers are assessed and an M:E ratio calculated. 
• Performed by a certified clinical pathologist.

Modified Myelogram Assessment

• Manual slide evaluation. 
• Performed by counting a minimum of 300 intact hematopoietic nucleated cells classified into proliferative (mitotic) or mature (non-mitotic) erythroid or myeloid cell populations or lymphocytes. 
• Any notable abnormalities of the sample and evaluated cell lines are recorded, megakaryocytes numbers are assessed and an M:E ratio calculated. 
• Performed by a certified clinical pathologist.

Myeloid-Erithroid (M:E) Ratio

• Manual slide evaluation. 
• M:E ratio evaluation of the bone marrow smear(s) is conducted by counting a minimum of 300 total cells of the erythroid and myeloid series and lymphocytes. 
• # Myeloid Cells (M)/# Erythroid Cells (E )= M:E ratio
