Immunophenotyping, a common application in flow cytometry, allows multiple cell surface markers to be simultaneously characterized on a per-cell basis.Immunophenotyping can be difficult by flow cytometry, however, when only a small number of cells are available. Flow cytometry immunophenotyping is used primarily to help diagnose and classify blood cell cancers (leukemias and lymphomas) and to help guide their treatment. (2018 October 17, Revised). What is Immunophenotyping?. 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.

These antigens are also used by the newer myeloma drugs to identify specific cancer cells. The volume of fluid necessary to phenotype the lymphocytes or blasts in spinal fluid depends upon the cell count in the specimen. She just said I needed another pap in 6 months.

Flow Cytometric Immunophenotyping Is Sensitive for the Early Diagnosis of De Novo Aggressive Natural Killer Cell Leukemia (ANKL): A Multicenter Retrospective Analysis. "What is Immunophenotyping?". This study examines the immunohistologic profiles of a large series of histologically proven benign and malignant lymphoproliferative processes in order to define immunophenotypic criteria useful in the diagnosis of non-Hodgkin's lymphoma. (Reviewed 2010 December). Acute myeloid leukemias (AMLs) are hematologic malignancies with varied molecular and immunophenotypic profiles, making them difficult to diagnose and classify.

The prognostic value of immunophenotyping in AML is controversial [ 3]. The antigens on specific leukemia or lymphoma cells may remain the same over time.
