Your health care practitioner will consider the flow cytometry immunophenotyping results together with your clinical history, physical examination, signs and symptoms, as well as all laboratory tests to help make a diagnosis. Clinical features, laboratory findings, morphologic, cytogenetic features, and Epstein-Barr virus status were important factors for diagnosing aggressive NK cell leukemia. Application of these criteria to a series of nearly 500 cases of lymphoma indicated that over 90% of B-lineage and about 80% of T-lineage neoplasms manifested immunophenotypic abnormalities that could distinguish them from benign, reactive lymphoid processes. 1. In general, these criteria involved identification of abnormal expression or loss of antigens in B- and T-lineage populations. Specific groupings of these antigens are normally present on or within WBCs and are unique to specific cell types and stages of cell maturation. 88184-Flow cytometry; first cell surface, cytoplasmic or nuclear marker x 1, 88185-Flow cytometry; additional cell surface, cytoplasmic or nuclear marker (each), 88187-Flow Cytometry Interpretation, 2 to 8 Markers (if appropriate), 88188-Flow Cytometry Interpretation, 9 to 15 Markers (if appropriate), 88189-Flow Cytometry Interpretation, 16 or More Markers (if appropriate), Normal Reports | ( 2015).

Abnormal patterns of expression for at least one antigen was found in 91% of RA/RARS cases and in 74% of RAEB. A pathologist, often one specializing in the study of blood diseases and/or blood cell cancers (a hematopathologist), will consider the results from the complete blood count (CBC), differential, blood smear, bone marrow findings, and flow cytometry immunophenotyping as well as other tests in order to provide a diagnostic interpretation. Unauthorized use of these marks is strictly prohibited. The main advantages of IHC are the possibility to correlate antigen expression with cell morphology and tissue architecture and the ability to detect a relatively low number of neoplastic cells, such as in Hodgkin's lymphoma (HL) or T-cell-rich large B-cell lymphoma (TCRBCL). None of the tested antigens were linked to treatment outcome. What is Immunophenotyping?. Understanding Laboratory Tests.
