Beckman Coulter Recalls

Hazard: Beckman Coulter has identified that the UniCel DxI 600/800 systems with linear slide PnP gantries running software versions 5.7 and up faced incorrect PnP X-motor current settings where the PnP X-motor current incorrectly resets to 1.5A (instead of the required 2.0A) because the software overwrites the factory setting during installs or upgrades. This anomaly causes increased PnP motion errors which could lead to delays in reporting patient sample results if unnoticed.

Hazard: Beckman Coulter identified that the Unsaturated Iron Binding Capacity (UIBC) assay is not meeting their labeled hemoglobin interference claims of no significant interference (i.e., less than 10%) up to 200 mg/dL hemoglobin as indicated in their instructions for use. Initial internal testing confirmed that samples with low UIBC levels failed the claimed hemolysis interference specifications with reported biases up to -43.6 % UIBC when hemolyzed serum samples contained 200 mg/dL hemoglobin.

Hazard: A specific lot of bovine serum albumin (BSA) used for manufacturing of coated tubes (CT) that are included in the Estrone RIA kit lots caused different affinity of manufactured coated tubes to patient samples, causing falsely increased assay results for the impacted Estrone RIA kits.

Hazard: 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.

Hazard: 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.

Hazard: 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.

Hazard: 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.

Hazard: 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.

Hazard: 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.

Hazard: 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.

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

Hazard: 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.

Hazard: 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.

Hazard: 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.

Hazard: 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.

Hazard: 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.

Hazard: 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.

Hazard: 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

Hazard: 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.

Hazard: A software error caused an increase in tray gripper motion errors that causes intermittent hard stops and a delay in patient results.

Hazard: Identified reagent lots are experiencing a high rate of calibration failures with failure code of "Max Iterate" on Access 2 and UniCel Dxl Immunoassay Systems. Reporting of results may be delayed due to the time required to achieve a passing calibration curve.

Hazard: Beckman Coulter has identified that some Access PTH reagent packs from lot 339071 may be over- or under-filled in well 0. The dispensed material in well 0 could be above or below specification, risking sealing issues, contamination, instrument errors, delays, or inaccurate results with a negative bias and increase in imprecision. The issue was confirmed on 10 April 2024 by Beckman Coulter through an internal non-conformance (NC-INT-66585). The well 0 scale on the filling line began malfunctioning on the fill immediately before PTH. The malfunction was not noticed until the majority of PTH was filled.

Hazard: Beckman Coulter, Inc. is recalling their Access hsTnI assay, a medical device by correction. The reason for the recall is: high troponin antigen (>55,000 pg/mL) can contaminate an analyzers probe and cause inter-assay carryover due to insufficient washing. The contamination can cause a falsely elevated Access hsTnI result in subsequent sample(s) which can impact patient care (potentially but not limited to unnecessary coronary imaging or diagnostic catheterization) if the result is near the medical decision points.

Hazard: The reason for the recall is that EDTA and lithium heparin plasma samples that are stored in the DxI 9000 Access Immunoassay Analyzer sample wheel for a prolonged period before performing the intact PTH (parathyroid hormone) test may produce falsely decreased intact parathyroid hormone results. This could lead to a missed diagnosis, a delay in treatment, or inappropriate clinical management, depending upon the patient s clinical condition.

Hazard: The Access Cortisol assay protocol file (APF) applies an incorrect calibration curve acceptance parameter at the S1 calibrator level that can lead to a high rate of calibration failures which can vary by reagent lot number. Calibration failure would lead to delay of measurement results reporting and potential injuries.

Hazard: IFUs for the device incorrectly states the biotin interference was remediated. The issue could result in potentially false-low results.

Hazard: Firm identified two lots of reagents that are not meeting the sensitivity statement in the IFU

Hazard: Certain lots of Access TSH reagent packs may produce erroneously low TSH (thyroid-stimulating hormone) results.

Hazard: Beckman Coulter has become aware of an increase in customer complaints for intermittent IRISpec CB negative glucose control failure, resulting in false positive control results when used in conjunction with iChemVELOCITY Urine Chemistry Strips (PNs 800-7204 and 800-7212) on the iChemVELOCITY Analyzer. This issue may delay the reporting of patient results, with a worst-case scenario of a delay in diagnosis or treatment of metabolic disorders, kidney function abnormalities, urinary tract infections, and liver function.

Hazard: When the DxI 9000 Access Immunoassay Analyzer with system software version 1.16.2 and prior is configured to automatically request a calibration order, the instrument can process the order with expired calibrator material. If the calibration curve is generated with an expired calibration material lot, this may lead to a hazardous situation of erroneously high or low patient results reported to the physicians.
