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.

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

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.

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.

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.

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.

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.

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

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

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

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.

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.

Beckman Coulter is recalling the DxI 9000 Access Immunoassay Analyzer due to undersized Pneumatics Tubing in the reagent storage module causing air leaks, compressor failures or sample processing errors. Four complaints were filed for this event that led to Beckman Coulter finding undersized tubing in stock and initiated corrective actions. Use of the affected device may result in errors leading to delay of results.

Beckman Coulter manufacturing discovered cracks around a threaded insert on the bottom of the Internal Wash Buffer Tank that is used within the Wash Buffer Supply Drawer on the DxI 9000.This can result in leaking, leading to delays in reporting patient test results, exposure to physical and chemical hazards, and damage to equipment or the environment.

When a DxI 9000 Access Immunoassay Analyzer is connected to a Laboratory Automation System (LAS) and is running with the system software versions 1.17.0 and below, the analyzer does not send a message to the LAS when the sample wheel is full, and the LAS continues sending samples despite the limited capacity to process new samples. Therefore, sample tests may be aliquoted but not processed when the number of tests associated with onboard patient samples exceeds the throughput limit. If this issue occurs test results are flagged with a sample wheel timeout (SWT) error flag, and there may be a delay in reporting test results which could lead to a delay in patient treatment.

Beckman Coulter, Inc. has identified a rise in reagent carousel motion errors in Access 2 Immunoassay System Analyzers that appear to be caused by misaligned index wheels housed within the reagent carousel module. Customers affected by this issue may observe an increase in reagent carousel motion errors or QSMC errors that occur while unloading or loading reagent packs during system initialization and sample processing, which causes a non-operational system status and cancels tests; and patient results may be delayed if these errors cancel test processing.

The reason for this recall is Beckman Coulter has determined that when a DxI 9000 Access Immunoassay Analyzer is connected to a Laboratory Automation System (LAS); is running with the software versions 1.17 and below; and a sample tube is sent from the LAS to DxI 9000 Access Immunoassay Analyzer, an out of sequence message will be sent from the Analyzer to the LAS. This issue may result in multiple error messages (i.e., a sample pick and place (PnP) error or a no result obtained (NRT) flag may be displayed) and subsequently a risk of delays in processing/reporting patient test results and patient treatment.

LIH Influence check settings for Lipemia are incorrect which may result patient samples being reported as false low results or cause a high result to report as normal

The analyzers were built with nonconforming USB cables made with brass contacts instead of specified gold contacts. Brass contacts may corrode over time, leading to loss of internal instrument communication and delayed patient results.

Beckman Coulter is recalling their DxI 9000 Access Immunoassay Analyzers, an in vitro diagnostic device used for the quantitative, semi-quantitative, or qualitative determination of various analyte concentrations found in human body fluids, by correction. The reason for the recall is: Beckman Coulter has determined that the DxI 9000 Access Immunoassay analyzer accepts calibrator values scanned from multiple calibrator cards when an operator configures a new calibrator lot. The analyzer accepts the calibrator lot values from any scanned calibrator card, regardless of the assay test code or calibrator material lot number. The software is not validating the integrity of each calibrator barcode scanned to ensure they are all from the same calibrator card. This includes all software versions and all DxI 9000 instruments that are currently in the field. This issue does not impact calibrator material with 2D calibrator card barcodes. This may cause a failed calibration curve. The health risk to patients is dependent upon the analytes that could be impacted by the error, to include receiving delayed or erroneous results. The issue was identified by Beckman Coulter while conducting a field action on DxI 9000 Access Immunoassay Analyzers.

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.

On 07 February 2024 Beckman Coulter made the decision to conduct a field action on Access Substrate (81906) lots: 234600, 337984, 338040, 338214, 338229, 338289, 338322, 338333, 338451, 338587, and 338538. Beckman Coulter has identified that Access Substrate bottles in the identified lots were released from manufacturing without labels. Missing label may cause some patient results reporting delay but will not cause any errorreous results. However, because labs are required to have redundancy such that delay would not significantly impact clinical management and because the defect is easily recognized by the user, the probability of harm is remote.

Four lots of Access Total T4 reagent lots demonstrated imprecision outside of the 10% specification which may result in erroneous or delayed results.

There are potential performance issues found in the DxI 9000 Access Immunoassay Analyzer, including: 1) Access Ultrasensitive Insulin users who configure SI units (pmol/L) applies an incorrect conversion factor; 2) System provides numerical results that are below the lowest reportable result if laboratory chooses to report assay results in units of measurement other than the defined default units; 3) A result of 0 incorrectly reported when the system utilizes an expression that utilizes non-numerical symbols (e.g., > or <) to derive a calculated test as part of result reporting; 4) Reserve volume is enabled and the assay LIS code is not the same as the assay Test ID. These issues could potentially lead to erroneous results or delay reporting results for multiple analytes.

There is an issue with the Access Ultrasensitive Insulin assay protocol file (APF) for use with the DxI 9000 Access Immunoassay Analyzer (APF 182 test definition version 6.7 and below). The Access Ultrasensitive Insulin APF applies an incorrect conversion factor when converting from system default units of ¿IU/mL to the International System of Units (SI units) of pmol/L.
