Flow cytometry is used in diagnosis and classification of B-cell lymphoproliferative disorders, measuring expression level of target antigen and monitoring of minimal residual disease. Immunological phenotype of tumor B cells is not always in accord with classical characteristic and it makes complicated the interpretation of data, and therefore there is a need to find additional informative markers. Using new monoclonal antibodies to CD160, CD200 and LAIR-1 enhances the diagnostic capabilities of flow cytometry.

Keywords: B-cell lymphoproliferative disorders, markers CD160, CD200, LAIR-1, multiparameter flow cytometry.
