The BD FACSCount™ System is a complete, dedicated system for automatically counting CD4+, CD8+, and CD3+ T lymphocytes. These cell counts are used to monitor the immune status of persons infected with HIV. The compact, self-contained system, incorporating instrument, reagents, and controls, eliminates the need for hematology results to obtain absolute count values and reduces variability or simplifies the sample preparation procedure.
The BD FACSCount System uses whole blood, eliminating lyse and wash steps. A unique software algorithm automatically identifies the lymphocyte populations of interest. Easy-to-use, cost effective, and reliable in the clinical laboratory, the BD FACSCount System is designed to utilize the power and advantages of flow cytometry for the enumeration of absolute and percent CD4+ T-lymphocytes. Having one system giving both results should reduce the cost and thus increase access to CD4 testing for pediatric and adult patients.
