FEATURES

Easy to Install, Set Up, and Run with Confidence The BD FACSCount system is easy to install. 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. Quality control To validate laboratory practice and methodology, BD FACSCount™ control beads can be added to samples prepared with normal blood. 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. Simplified sample handling Sample preparation follows an easy three-step process. First, blood is added to a tube that contains pre-measured reagents. Then the sample is vortexed and incubated. In the second step, a fixative is added to the tube, and then it is vortexed and incubated. In step three, the sample is vortexed and run on the instrument. Easy three-step sample preparation Prepare controls and patient samples by adding blood, then fixative solution, to the reagent tubes.
