Epub 2018 Aug 6. Understanding Laboratory Tests. "What is Immunophenotyping?". (2013 December 11). 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. Accessibility 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. Ann Hematol. More practically, and although the relationships demonstrated only represent a fraction of homogeneous immunophenotypic subgroups, identification of such immunophenotypic features should prompt careful karyotypic examination, eventually using molecular biology analysis on non-growing cells. 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.

More importantly, there are newer classes of treatment options like CAR-T therapy, bispecific T-cell engagers, and monoclonal antibodies thatselectively target molecules like CD19 or CD20.
