99400-4
LaboratoryCD19+CD23+ cells/cells in Bone marrow
Definition
This assay can be used as part of an immunophenotyping analysis of B-cell neoplasms. The assessment of expression of cell markers such as CD23, CD79, CD22, CD38 and FMC-7, among others, can help to identify lineage and refine diagnosis and prognosis [https://onlinelibrary.wiley.com/doi/full/10.1002/cyto.b.21756] [PMID:30549186]
