(2008 December 1). no immunophenotypic abnormalities detected - salongmaria.se Flow cytometry may be used to characterize and count types of white blood cells in the evaluation of infectious diseases, autoimmune disorders or immunodeficiencies. These abnormalities were related to immunophenotypic markers as detected using a consensual panel of monoclonal antibodies allowing lineage assignment and investigation of myeloid marker expression on blast cells. Bone marrow immunophenotyping by flow cytometry in refractory cytopenia In these cases, LSC analysis is a methodology of choice because of its low sample requirements. While morphologic assessment of blood smears, bone marrow smears, and tissue sections remains the cornerstone of lymphoma and leukemia diagnosis and classification, immunophenotyping is a very valuable and important complementary tool. Among B-lineage populations the following features were associated with malignant histology: 1) light-chain-restricted B lineage, 2) light chain -B lineage, 3) Leu-1+ B lineage, 4) L60+ B lineage, 5) 41H+, Ki-67+ B lineage, 6) loss of pan-B antigens, and 7) LFA-1-B lineage.

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. The abnormal cells grow, but they do not fight infections or perform other functions like normal WBCs.
