Immunophenotyping by flowcytometry is fundamental to diagnose and subtype Acute Myeloid Leukemia. The objective of study to investigate immunophenotypes of different morphological FAB subtypes of AML. All newly diagnosed cases of AML(180 cases) on morphology that is presented to our hospital from January 2015 to December 2015 were included in study. Full panel of flowcytometric immunophenotyping was performed on BM and peripheral blood samples. Expression of myeloid markers and aberrant markers are studied. The results highlighted the correlation of a morphological FAB subtypes with immunophenotyping markers
