Beckman Coulter has received complaints of erroneous Vitamin B12 results when using Access Vitamin B12 Reagent lot 439850. The affected reagent lot may cause erroneously low or high Vitamin B12 results, leading to a delayed or improper diagnosis and/or repeat testing.

Due to a software issue, the software may incorrectly process the date of birth (DoB) received from the Laboratory Information System (LIS) and when the DoB is set to 01/01/1900 or left empty, REMISOL Advance may incorrectly identify a patient as a newborn, affecting the execution of validation rules based on incorrect reference ranges. The test results are not changed by this software defect and are accurately displayed by REMISOL Advance; however, the evaluation flagging of the results may be affected. This issue may lead to wrong reference range calculations and can result in erroneous flagged results being auto validated and uploaded to LIS.

Analyzer has calibration issues where curves switched from passed to failed due to system errors during aspiration. This anomaly causes erroneous results and delays if unnoticed. RLU values may be misinterpreted as valid measurements by LIS.

A new motor/encoder and cable was introduced into instruments manufactured starting with serial number 300141 incorrectly. This incorrect installation is introducing error codes for the Dxl 9000 which prevents the assay from being performed and a delay in results from being generated, and may require field service to resolve the delay.

A new software update (v1.20) is introducing error codes for the Dxl 9000 which prevents the assay from being performed and a delay in results from being generated, and may require field service to resolve the delay.

Inadequate preventative maintenance (PM) performed on the scales of the RPL5 fill line, led to splashing (cross-contamination) between the wells of testosterone reagent packs lot 538081, which could potentially result in up to a 34% increase or a 23% decrease in patient results.

Beckman Coulter is recalling their DxC 500 AU Clinical Chemistry Analyzer because a software error causes the analyzer to not run a requested calibration order in the following scenario: when a reagent blank or calibration is ordered during sample processing and then any of the components (R1 and/or R2) depletes to zero tests, the analyzer will not be able to complete the calibration request, and the calibration order will remain pending. No further calibration orders can be processed for any assays, and the instrument refuses to accept further sample processing order after the existing calibration curves are expired. Although in-process tests will be completed, this error can cause a delay in reporting subsequent test results. No further calibration orders can be processed for any assays which may cause a delay in reporting test results.

The reason for the recall is incorrect sample barcode identification and processing errors that result in the reporting of erroneous and delayed results.

When DxI 9000 Access Immunoassay Analyzer is connected to a host system (laboratory information system (LIS) or middleware) and has accumulated canceled QC test results that were not sent by LIS, the analyzer may lose communication with the host system. The lost connection interrupts sample processing, which delays reporting patient test results and may subsequently delay patient treatment.

Ground screws on Dxl 9000 PCB boards may cause electric shorts, leading to smoke and potentially delaying patient results. Smoke also poses a hazard to equipment and users.

Beckman Coulter has determined that device software versions V1.3, V1.4, V1.4.1, V1.4.2, V1.4.3. have a defect due of which, when all constituent tests of a calculated result are rerun, either manually ordered by the operator at the analyzer or automatically triggered by predefined rules in System Configuration, the calculated result will not be recalculated using the constituent tests rerun results. The system will report only the calculated result using the initial constituent tests results to the operator and LIS/Remisol. The issue was identified by Beckman Coulter internal engineering testing. The defect may cause a delay in reporting patient results.

the DxI 9000 encoder wheel was misaligned on the motor shaft, leading to increased slippage errors and causing the instrument to stop, posing a high safety risk due to potential delays in patient results.

Beckman Coulter identified that an issue for DxI 9000 tip stocker interface (TSI) and reagent storage interface (RSI) boards with the firmware version 1.1.0.0 can cause sub-system communication failures. This failure could result in a delay in reporting patient results.

Beckman Coulter identified that an issue for Access 2 Sample Motors (B48016) due to improper alignment, causing the motors to rub against the sample wheelbase plate and index sensor. The issue was traced to a worn tool used in production (at the supplier), affecting Access 2 sample motors. This could lead to a potential delay in reporting patient test results.

The DxI 9000 Access Immunoassay Analyzer wash wheel mixer may not spin freely within the idler pulley housing. When the problem occurs, the analyzer may generate a system event for a Wash Wheel Dispense Arm Spin Mixer Error that is displayed on the navigation bar in the User Interface. The analyzer enters the red system status and will generate a SYS flag. The tests that are in progress may be cancelled and may cause a delay in reporting patient results

Affected lot (439363) exhibited a negative dose drop of -22% with native patient samples compared to alternate reagent lots. Patient samples tested with the affected lot may demonstrate repeatable falsely decreased results, which may lead to improper diagnosis or repeat testing.
