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. 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.
