The instrument operates from a standard electrical outlet, requiring no hardware adjustments or calibration. Only minimal training is needed to set up the instrument and to run samples. Simple prompts on the display guide operators through testing, from input of patient information to final results. The software automatically identifies the lymphocyte populations of interest and summarizes patients’ results in a printed sample report. Quality controls in the software ensure that reported results are accurate by detecting and flagging error conditions and suppressing results when control limits are exceeded. Results are objective, requiring no interpretation or subjective analysis by the operators. BD FACSCount fluorescent reference beads are included in the reagent tube, and ensure accurate enumeration of lymphocytes of interest with no operator intervention. The control run generates a detailed analysis in a printed report summarizing system performance. The result of the last control run is reported on subsequent sample printouts to help determine linearity and pipetting accuracy. Since absolute counts are calculated from directly measured cell counts and reference bead counts on the BD FACSCount system, no additional analysis on a hematology analyzer is necessary.Sample preparation follows an easy three-step process. First, blood is added to a tube that contains pre-measured reagents.

Figure 1-1 BD FACSCount system workstation coring station electronic pipette BD FACSCount instrument Principle of Operation Simply follow the whole blood staining procedure in Chapter 5 to prepare samples. Then run the samples on the BD FACSCount instrument. A built-in screen displays instructions for operation. The procedure requires minimal sample handling. When whole blood is added to the reagents, fluorochrome-labeled antibodies in the reagents bind specifically to lymphocyte surface antigens, and a fluorescent nuclear dye binds to the nucleated blood cells. After a fixative solution is added to the reagent tubes, the sample is run on the instrument.

During sample acquisition, the cells come in contact with the laser light, which causes the fluorochrome-labeled cells and fluorescently dyed cells to fluoresce. This fluorescent light provides the information necessary for the instrument to identify and count the lymphocytes and CD4 lymphocytes. 12 BD FACSCount System User s Guide for Use with BD FACSCount CD4 Reagents 13 In addition, the reagent tubes also contain a known number of fluorescent reference beads. A precise volume of whole blood is stained directly in the reagent tube. Results include CD4 counts and CD4 percentages, and are printed immediately after samples are run. Intended Use BD FACSCount CD4 reagents are used to enumerate the absolute counts of CD4 T lymphocytes and the percentage of lymphocytes that are CD4 T lymphocytes in unlysed whole blood (CD4 counts and CD4 percentages). The reagents are intended for in vitro diagnostic use on a BD FACSCount instrument. Equipment and Materials Required The following materials are used with the BD FACSCount system.
