      In combination with the BD OneFlow™ LST, it is intended as an aid in the diagnosis of chronic lymphocytic leukemia (CLL) and other B cell chronic lymphoproliferative diseases.

       

       

      Overview

      The BD OneFlow™ B-CLPD T1 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™ B-CLPD T1 is intended for flow cytometric immunophenotyping of B cells in peripheral blood and bone marrow as an aid in the diagnosis of chronic lymphocytic leukemia (CLL) and other B cell chronic lymphoproliferative diseases.

       

      Other reagents belonging to the BD OneFlow™ Solution are BD OneFlow™ Lymphoid Screening Tube (LST), BD OneFlow™ Plasma Cell Screening Tube (PCST), BD OneFlow™ Plasma Cell Disorders (PCD) Tube and BD OneFlow™ Acute Leukemia Orientation Tube (ALOT).

      FEATURES

      The BD OneFlow™ B-CLPD T1:

      • Is a preconfigured single-use, ready-to-use 8-color reagent provided in a single tube
      • Is a classification tube that is used for specimens with B lineage populations needing further investigation in combination with the BD OneFlow™ Lymphoid Screening Tube (LST)
      • Is available in the 20 test/box size (4 pouches of 5 tubes each)
      • Allows for reagent visual identification with boxes, pouches and tubes color coded with a lighter blue color than the one identifying BD OneFlow™ LST. The blue color (dark and light) identifies the BD OneFlow™ B-cell Chronic Lymphoproliferative Disease Panel

       

       

       

      The BD OneFlow™ Reagents increase efficiency by simplifying instrument standardization, reducing the time to prepare the instrument as well as the technical burden and training needs.2

      For BD FACSLyric™ Flow Cytometer users:

      • BD® CS&T IVD Beads standardize setup and monitoring for consistent performance and ensure reproducibility through Universal Setup
      • BD® FC Beads (7-Color, 5-Color and 2-Color Kits) support consistency of results, eliminating the need for using cells for compensation
      • BD® CS&T Beads and BD® FC Beads kits necessary for instrument setup and compensation can be used for other BD CE-IVD assays on the BD FACSLyric™ Flow Cytometer

       

      For BD FACSCanto™ II Flow Cytometer users:

      • BD FACSDiva™ CS&T IVD Beads standardize setup and monitoring for consistent performance and ensure reproducibility with Application Settings
      • BD OneFlow™ Setup Beads ensure data accuracy and reproducibility by providing assay-specific target values, as per EuroFlow™ SOPs.3
      • The specifically designed BD® FC Beads 8-Color Kit eliminates the need for using single-vial reagents and cells for compensation
