Intended as an aid in the diagnosis of hematological disorders 




The BD OneFlow™ LST is part of the innovative BD OneFlow™ Solution, a comprehensive set of reagents, setup beads, protocols and assay templates to reproducibly set up the flow cytometer and stain, acquire and analyze patient specimens for immunophenotyping of normal and aberrant cell populations. It is built on the research and validation work of the EuroFlow™ Consortium on the characterization of hematological malignancies for improved accurate diagnosis.1


The BD OneFlow™ LST is intended for flow cytometric immunophenotyping of normal and aberrant mature lymphocyte populations of B, T and NK cell lineages in peripheral blood, bone marrow and lymph nodes, as an aid in diagnosis of hematological disorders.


Other reagents belonging to the BD OneFlow™ Solution are BD OneFlow™ B-cell Chronic Lymphoproliferative Diseases Tube 1 (B-CLPD T1), BD OneFlow™ Plasma Cell Screening Tube (PCST), BD OneFlow™ Plasma Cell Disorders (PCD) Tube and BD OneFlow™ Acute Leukemia Orientation Tube (ALOT).

Supporting Evidence

The EuroFlow “LST detected aberrant B-, T-, or NK-cells immunophenotypes in 149/150 (99.4%) of B-CLPD and in 78/83 (94%) of T/NK-CLPD with an overall frequency of 97.4%."1


Results from the clinical trial study (BD OneFlow™ LST Instructions for Use) show that the BD OneFlow™ LST in combination with the BD OneFlow™ B-CLPD T1 gave 100% (101 of 101) overall agreement in classifying patients as having CLL (54 of 54 concordant) and in identifying patients with other B cell chronic lymphoproliferative diseases (47 out of 47 concordant) when compared with the EuroFlow system. Furthermore, interpretation of the BD OneFlow™ Solution results was highly concordant to diagnostic truth.
