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.

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.

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 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.

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

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.

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

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 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.

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.

Beckman Coulter has become aware that the cannula, which is found in the Flowcell and the iQClear Rinse Waste Well Assembly, may rust. Rust from the cannula has the potential to generate erroneous results.

The firm has investigated and confirmed that when DxI 9000 is connected to Laboratory Information System (LIS, host), the sample barcode presented may be ignored and replaced with a sample ID that was previously in the same rack and position. This will cause a delay of result to the sample currently presented to the system (Sample B) and may result in an erroneous test result for the prior sample (Sample A), which gets associated with the results of sample B.

It has been determined through an internal investigation that the alternate Access Thyroglobulin calibrator cards for use with the Thyg reagent packs distributed in April 2023 will cause a decrease of approximately 11% in patient results.

Lipemic interference failed to meet the performance specification listed within the IFU.

Beckman Coulter, Inc. is recalling Ringed DxI Reaction Vessels (RVs) as part of Unicel DxI Immunoassay System (600, 800 series). The reason for the recall is that the firm has identified 3 lots of RVs that failed an internally used service test to evaluate washing efficiency. Increased relative light units (RLU) suspected to be caused by the resulting rough interior surface may lead to artificially falsely elevated results for susceptible tests, in particular, sandwich assays including, but not limited to, hsTnI, Hybritech p2PSA, IPTH/IPTH IO.

The reagent lot produces elevated results (approximately >30%) in some (15-20%)patient samples that do not correlate with the results of other thyroid markers nor Free T3 results generated on other platforms. This introduces a risk of the positive bias not being detected by QC with the potential that clinical correlation with other thyroid function tests will be inconsistent requiring additional testing; however the clinical assessment and treatment decisions are not made in isolation on a single test result especially, in the setting of thyroid function testing. False positive test results could lead to a euthyroid patient being interpreted clinically as having elevated thyroid function (hyperthyroid) or a hypothyroid patient being within the normal range. Such misdiagnoses may lead to inappropriate treatment of a euthyroid patient with anti-thyroid medications or hypothyroid patient not getting sufficient treatment since their free T3 test result demonstrates them to be in the euthyroid range.

An increased incidence of damage to the nut band from a new vendor (Boamax) has led to an increased volume of complaints from consignees regarding wash arm motion failures, system check failures, and/or assay performance leading to a remote probability of delayed results or reporting erroneous patient results. The subject nut bands were found to not meet the firm's specifications for hardness and had the incorrect material grain direction. Affected instruments were manufactured from December 28, 2017 to October 19, 2022 or had their nut bands replaced during the same period.

Use may cause a maximum positive bias up to 30.38% in low magnesium patient samples. The impact is only to the clinical interpretation of magnesium results in the presence of lipemia.

Cholesterol Reagent may fail with Out of Calibration Range Low (OCR Low) and/or Back to Back (B/B) errors. Low quality control recovery failures may be observed after passing calibration. Brown particulates in compartment C of the reagent cartridge may be observed. Continued use may lead to, 1) failed QC and/or calibrations, 2) Erroneous low Cholesterol patient results.

Missing splash guard which may expose users to hazardous materials. .

Through customer feedback, testing a sample with cardiac troponin I concentration that are >270,000 pg/mL may cause carryover into the hsTnl reagent pack. The carryover is caused by sample-to-pack carryover predominantly into the particle well of the reagent pack by way of the probe. The particle well then becomes contaminated by the high sample from the probe. The extent of the carryover is dependent on sample concentration and frequency of high concentration samples.

There is a potential that sample carriers (w or w/o samples) within automated sampling system may transport samples to the outer lane which does not contain a physical barrier to restrain samples. Samples are dropped when they reach the end of the outer lane which could result in Delay in providing patient with appropriate medical treatment. New sample needs to be drawn.
