As mentioned, the immunophenotypic panels used evolved during the study, and not all antigens were studied in the entire MDS patient group . Immunophenotypic characterization of the leukemic cells has been widely used as a tool for diagnosis, classification and prognosis of leukaemia. ASCUS stands for Atypical Cells of Undetermined Significance,and basically means there were mild cellular changes and the the cause in unknown. 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. The results of flow cytometry or immunocytochemistry should always be interpreted along with the available medical history, clinical signs, imaging findings, and pathologic results of individual cases. In addition, reflex testing may occur to fully characterize a disease state or clarify any abnormalities from the screening test. Immunophenotype is a key parameter that is very valuable in predicting response to treatment as well as survival rates. This category is to be used to record an episode of elevated blood pressure in a patient in whom no formal diagnosis of hypertension has been made, or as an isolated incidental finding.
