Now, if an adult has a small number of mature B cells but also has a large number of immature B cells which are positive for CD19 (remember, CD19 is a B-cell marker) and also positive for both CD34 and CD20 (which identifies those cells are both immature and abnormal), then the personhasan immature B-cell leukemia known as B-lymphoblastic leukemia. Additional FISH or molecular testing may be recommended by the Mayo pathologist to facilitate diagnosis.

Diagnosis of leukemia or lymphoma is based on the visual examination of a blood smear and/or bone marrow biopsy and aspiration for the presence of certain cell types. . In fact, these two markers are not normally expressed together. 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. It can detect normal cells as well as abnormal cells whose pattern of markers are typically seen with specific types of leukemia and lymphoma. Williams and Wilkins Inc; 1994:939-969, 3. Disclaimer.
