[Importance of cytogenetics in the study of acute non-lymphoblastic leukemias]. It may be because the markers of interest are not available for flow cytometryor because fresh cells or tissue are not available (a requirement for flow cytometry immunophenotyping). Flow cytometric immunophenotyping is of great value to diagnosis of natural killer cell neoplasms involving bone marrow and peripheral blood. According to the European Group for the Immunological Classification of Leukemias (EGIL), AML can be immunologically defined by the expression of atleast two of the following myeloid markers: Based on this classification, one study researched the prognostic significance of various immunophenotypic subgroups in 177 adult AML patients. Immunophenotyping detects the presence or absence of antigens found on the surface or interior of blood cells. Pertinent clinical history including reason for testing or clinical indication.
