Event 94728

The reason for the recall is the pneumatic tubing used in the analytical pick-and-place (PnP) assembly cable may fully or partially disconnect from the flex cable assembly fittings during normal operation. The DxI 9000 Access Immunoassay Analyzer may generate a System Event log message that indicates PnP errors. Any cancelled tests will have an associated SYS flag. The analyzer may enter the Red-system status because of this issue. The analyzer also may not eject RVs, where unbound conjugate could potentially splash up on the sidewall of the RV, not being properly washed away, resulting in an artificially higher signal (RLU). The analyzer may not detect this splashing and continue with normal operation, which can cause false low or high erroneous results. Consequently, the analyzer may cancel in-progress tests. These errors could potentially cause delay reporting patient test results and patient treatments. The degree of the potential health hazard is dependent on the analytes that are potentially delayed, especially those analytes that would be used in the acute setting when treatment decisions are immediate. In this particular recall the highest risk analyte is troponin. Health consequences could include permanent impairment or possibly death if medical treatment decisions are delayed due to a delay in obtaining patient results. The issue was identified by Beckman Coulter Inc. manufacturing staff at their location in Brea California on February 29, 2024, during in-process acceptance inspection activities.
