Sysmex has received FDA clearance for the addition of residual white blood cell (WBC) counting to its XN-10 automated hematology analyzer with blood bank mode. The analyzer supports red blood cell (RBC) and platelet (PLT) component testing along with residual WBC counting in a single sample aspiration, with the goal of providing blood processing centers with increased efficiency, consistency, and accuracy. The XN-10 with blood bank mode features analysis of blood components with four different selectable profiles—two profiles for RBC concentrates and two profiles for PLT concentrates. Available as a single module (XN-1000BB) or twin co-primary analyzers (XN-2000BB), the scalable hematology analyzer may be installed as a tabletop analyzer or placed on wagons, and either model can accommodate the addition of the RU-20 reagent unit.
