  DxC 500i Clinical Analyzer Modules: 1. DxC 500 AU Module w/ISE, DxC 500i, Part No. C63522 2. DxC 500 AU Module, DxC 500i, Part No. C63521 3. Access 2 Module, DxC 500i, Part No. C13252

  Beckman Coulter has identified a software issue affecting DxC 500i Clinical Analyzers when testing plasma samples. Following user configuration of a Clinical Chemistry test to use units different from the system default, a subsequent configuration change and activation of the draft configuration in the System Configuration page may cause the analyzer to revert the test units to the system default setting without notifying the user. The system does Pre-Review Reminders Include OII and CDRHRecallGroup@fda.hhs.gov in any discussions on change/elevation of recalls to Class I classification and situations involving additional public communications (FDA and/or firm issued).

  Systems/units containing affected software/SQL BECKMAN COULTER CHEMISTRY ANALYZER AU480 REF / UDI-DI code: B96692 / 14987666542965 B96693 / 14987666542972 B12183 / 14987666540671 The AU480 Chemistry Analyzer measure analytes in samples, in combination with appropriate reagents, calibrators, quality control (QC) material, and other accessories. This system is for in vitro diagnostic use only.

  Certain AU480 chemistry analyzers, with Windows 10 IoT Enterprise 2021 LTSC PCs, may output the message System Stopped By Fatal Error: DBConnectionError AlarmDB when launching the instrument software, using PC pre-installed with Microsoft SQL Server 2022 Express. When this occurs, AlarmDB becomes unreadable and the instrument software cannot be started. This causes a delay in obtaining patient results.

  Beckman Coulter DxC 500i Clinical Analyzer Modules using software version 1.5 or lower: 1) DxC 500 AU Module w/ISE, DxC 500i, Part Number C63522; 2) DxC 500 AU Module, DxC 500i, Part Number C63521; 3) Access 2 Module, DxC 500i, Part Number C13252; DxC 500 AU Clinical Chemistry Analyzers

  a software defect in which the Parameter Package (PP) import logic overwrites all predefined calculated test rules, including those previously modified by the user, upon import of a new Parameter Package version. As a result, usercustomized calculated test rules revert silently to their default expressions, potentially generating erroneous patient test results without an explicit error notification. The issue affects instruments running software version 1.5 or lower and only occurs when a new Parameter Package is imported to a system that already has an existing Parameter Package onboard; new installations are not affected.

  Software defect, which allows the system to accept erroneous, non-monotonous calibrations for Spline-type assays. Cobas pro integrated solutions is an automated analyzer, intended for running qualitative, semi-quantitative and quantitative clinical chemistry and immunochemistry assays, as well as ion-selective measurements. When an erroneous calibration is active, the instrument fails to calculate new values and instead repeats the last successfully calculated result from any Spline-type assay for all subsequent measurements, leading to identical and erroneous patient and QC results. The defect could lead to patients receiving erroneous lab results, which could result in a remote risk of serious adverse health consequences. The following assays use spline type calibration and are affected by this issue: Cystatin C Gen.2, Ferritin Gen.4, Lipoprotein (a) Gen. 2, Lipoprotein (a) molarity, Vancomycin Gen.3, Kappa Free Light Chains Partner Channel, Lambda Free Light Chains Partner Channel, and fCAL turbo Partner Channel.

  Beckman Coulter UniCel Dxl 600, Part numbers: A71460, A71461, A30260; Immunoassay Method, Troponin Subunit

  Beckman Coulter has determined that, due to a potential communication issue, the analyzers listed above may not successfully restart following a standard shutdown, even after multiple attempts. If this issue occurs, the instrument will be unable to complete initialization and transition to Ready mode and the instrument will not process patient samples, QCs or calibrators. This causes delayed results.

  Alinity ci-series System Control Module (SCM), REF: 03R70-01, 03R70-20

  Abbott Laboratories is recalling their Alinity ci-series System Control Module, a chemistry/immunoassay anayzer, by correction. The reason for the recall is potential performance issues found in the Alinity ci-series System software versions 3.6.1. and lower that could lead to erroneous results for multiple analytes. The issue was identified by Abbott during the internal testing of complaint investigations.

  Access 2 Reaction Vessels, individual, disposable, plastic tubes used to process patient, quality control and calibration samples on the Access 2 Immunoassay system, Catalog Number 81901

  It has been determined that certain lots of Access 2 Reaction Vessels may contain manufacturing deformities. The bottom (round end) of the Reaction Vessel may have a small protrusion or hair like deformity. This could cause causing instrument errors (e.g., pipetting, rake, wash carousel errors) that could delay patient results.
