Anders PM, Montgomery ND, Montgomery SA, Bhatt AP, Dittmer DP, Damania B. J Clin Invest. (Updated 2014 March 23). MeSH 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. This site needs JavaScript to work properly. 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. In these cases, LSC analysis is a methodology of choice because of its low sample requirements. Sometimes pieces of the abnormal myeloma protein are filtered through the kidney into the urine. Additional FISH or molecular testing may be recommended by the Mayo pathologist to facilitate diagnosis. Immunophenotyping is widely used for the following reasons: Two types of tests are used in immunophenotyping: The choice of test is based on the type of sample: Heres a brief overview of the two types of test methods: In flow cytometry, the sample may range from blood, fluids in the body cavity (such as peritoneal or pleural fluids), bone marrow, or solid tissues in liquid media. The interpretation will be based on markers tested in increments of 2 to 8, 9 to 15, or 16 and greater. Please enable it to take advantage of the complete set of features!
