Safety & Recalls

Synced live from the FDA openFDA API.

• RECALL

  An internal investigation has determined that due to defective sub-components within the gantry assembly, a z-axis CAD movement motion error may occur and cause an analyzer to enter a Not Ready or Paused state, leading to a delay in obtaining results.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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

• RECALL

  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.

• RECALL

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

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  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 ma

• RECALL

  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.

• RECALL

  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

• RECALL

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

• RECALL

  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.

• RECALL

  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.

• RECALL

  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.

• RECALL

  IRISpec CA failures for glucose.

• RECALL

  The Leukocyte and Compensation pads were switched on some vials of lot number 7212269M of the iChem VELOCITY Strips.

• RECALL

  When racks are front-loaded onto the sample presentation unit while samples from the automation line are being processed, a scheduling error within the software can cause mishandling of samples during the creation of an aliquot and lead to incorrect results being generated. Affected samples typically yield non-reproducible falsely decreased results by up to 100%, however the potential for falsely elevated results cannot be ruled out.

• RECALL

  Falsely elevated (false positive) urobilinogen patient results due to an increase in the sensitivity of the urobilinogen reaction.

• RECALL

  Complaints received of sporadic erroneously elevated platelet results without flags or system messages. Thrombocytopenia may go unrecognized.

• RECALL

  There is a possibility of a data acquisition disruption that may cause an unusual light scatter event pattern for the white blood cell differential that may not have a system flag and/or message. The events associated with the unusual light scatter pattern may be incorrectly removed from analysis which can result in an erroneous differential result.

• RECALL

  Beckman Coulter is recalling the Access 2 Family of Immunoassay Systems because a circuit board that controls motor functions can affect device positioning on the pipettor and incubator belt while the instrument is running. The position errors cause the instrument to stop running and cancel tests that are in process.

• RECALL

  Beckman Coulter has determined that additional clarification for the Blast Suspect messages is necessary. In rare situations, the UniCel DxH 800 and DxH 600 Coulter Cellular Analysis System may not flag or detect blasts in some blood samples. This is due to limitations in the available technology as well as sample limitations.

• RECALL

  Iris International noted loose or missing analyte pads found in several locations (strip vial, strip provider module, strip conveyor system or waste container) that are undetectable by the iChemVELOCITY System.

• RECALL

  Iris International is recalling the iChem 10 SG Urine Chemistry Strip because of false positive leukocyte result for samples that are truly negative.

• RECALL

  Beckman Coulter is recalling the Sample Probe Cable because nonconforming sample probe cables may been installed on newly manufactured and/or recently serviced UniCel DxI 600 and 800 Access Immunoassay Systems, UniCel DxC 660i, 680i, and 860i, and UniCel DxC 880i Synchron Access Clinical Systems instruments. Use of a nonconforming sample probe cable can casuse a delay in reporting results, but wi

• RECALL

  Beckman Coulter is recalling the UniCel DxH800 and UniCel DxH600 Coulter Analysis Systems because the optical degradation may potentially cause a delay in reporting results for nucleated red blood cells (nRBC), automated white blood cell differential and the reticulocyte.

• RECALL

  Beckman Coulter is recalling the UniCel DxH 800 Coulter Cellular Analysis System because the NRBC, Differential or Reticulocyte mix chamber drain ports may become plugged by rubber pieces from specimen tube caps, and result in biohazard or chemical exposure and/or the potential for generating incorrect results.

• RECALL

• RECALL

  The recall was initiated because Beckman Coulter has confirmed that the UniCel Dxl and DxC Access Immunoassay Systems had field modifications to the aspirate and dispense probe assemblies.

• RECALL

  The recall was initiated because Beckman Coulter identified unexpected high particle counts in the lots of DxH Cell Lyse listed. These lots may generate high background counts; could result in a falsely elevated Total Nucleated Count (TNC) of up to 50 cells/L; or may also result in recovery of TNC values that were higher than expected for Level 1 of the Body Fluid Control.

• RECALL

  The recall was initiated because Beckman Coulter has confirmed that the probe wash collar tubing may become stretched or trapped at the Sample Aspiration Module (SAM) during routine use of single-tube presentation station. When the tension on the tubing is severe, the tubing may not be able to return to its home state and may pull the wash collar out of alignment with the aspirate probe. The misal

• RECALL

  The recall was initiated because certain Access immunoassays can produce inaccurate results when performed within the published UniCel DxI Immunoassay Systems* room temperature operating specification of 18 degrees C to 32 degrees C (64.4 degrees F to 89.6 degrees F). An increase in room temperature causes assay results for some assays to decrease, while results for other assays increase with an i

• RECALL

  The recall was initiated because Beckman Coulter has confirmed the auto prune will not remove patient results if the patient record includes demographics where the results are less than 30 days old.

• RECALL

  The recall was initiated because the DxH 800 may fail to meet the carryover specification for the WBC Differential (DIFF) when the WBC is greater than 70 X 10 to the 3rd power cells/micro L (70 X 10 to the 9th power cells/L). Beckman Coulter indicated the DIFF% carryover is unlikely to have clinical impact.

• RECALL

  The recall was initiated because: The DxH 800 may fail to meet the carryover specification for NRBC% when the WBC is greater than 50 X 10 to the 3rd power cells/micro L (50 X 10 to the 9th power cells/L) Beckman Coulter indicated the NRBC% carryover is unlikely to have clinical impact.

• RECALL

  The recall was initiated because: The handheld barcode scanner does not read barcode labels using NW 7 symbology. Impact: Specimens with NW7 labels cannot be read by the handheld scanner.

• RECALL

  The recall was initiated because: Specimen tubes may fall out of a Type A cassette (PN A53551, kit of 20) when the analyzer inverts the cassette in the mixing station, or when an operator manually inverts a cassette The impact: - Specimen tubes may fall out of cassettes and be misplaced inside the instrument - Specimen tubes may break upon impact, causing possible biohazard exposure - Patien

• RECALL

  The recall was initiated due to Beckman Coulter receiving a report of results that were associated with incorrect patient identifications when two sample racks advanced into the sample presentation area in one push. The first rack of the two was not scanned. This is referred to as a "pushed pair." If a pushed pair event occurs, results may be associated with the incorrect patient identification.

• RECALL

  There is a possibility that a specimen could be diluted if a user requests Diluent Dispense while specimens are being automatically processed in cassette presentation. The dilution may cause erroneous results. IMPACT: Erroneous results from a diluted specimen could impact clinical decision making in cases such as blood transfusion, chemotherapy or antibiotic administration- particularly for popu

• RECALL

  Sharp edges on drawer slides within the DxH800 Floor Stand (Cabinet) may expose operators to physical injury while replacing reagents and waste containers. IMPACT: There is potential for exposure to blood borne pathogens such as HIV, HBV, and HCV.

• RECALL

  For Panels containing CBC: The RBC and HCT are improperly corrected and not flagged when there is a WBC Pump Failure and the WBC ~ 140x103/uL. For Body Fluid Panels: The RBC is improperly corrected and not flagged when there is a WBC Pump Failure. IMPACT: Erroneous RBC and/or HCT could affect the interpretation and management of patients at risk with various types of anemias.

• RECALL

  RETIC results may be invalid when the instrument user interface allows reflex processing of a pre-diluted specimen in the RETIC test panel. Beckman Coulter has validated pre-diluted specimen processing in CBC panels. RETIC test panel using pre-diluted samples has not been validated. IMPACT: The reticulocyte value is an indicator for assessing red cell production. Erroneous results could impact c

• RECALL

  Body Fluids results may be incorrectly interpreted by the Laboratory Information System (LIS). Body Fluid results ~ 1,000 celis/uL are reported using the US numeric separators to demark thousandths places (comma, ",") and partial units (decimal, "."). An LIS that uses non-US formats could interpret the comma as a partial units separator, which could lead to reporting erroneously low body fluid r

• RECALL

  Test results may have incorrect ranges. If a default sample type setting on the tests screen is changed while running Unicel DXI system software version 4.3, the new setting is not saved to the system database. The changed sample type setting will reset to the previously saved setting when power is interrupted to the system, or if an operator reboots the system. If the default sample type i

• RECALL

  Issue 1: The Diagnostic procedure, Simulate-CDNR Cycle, is not functioning properly. Impact: There is a potential for inadequate sample preparation of samples following the use of this Diagnostic function impacting WBC, Differential, Reticulocyte and/or NRBC results. Issue 2: Use of the Auto Prune function causes the deletion of Quality Control files. Impact: If the last run for a control lot

• RECALL

  The Corrective Action was initiated after Beckman Coulter confirmed three issues related to host transmissions with the UniCel DxH 800. This information only affects instruments interfaced to a host system.

• RECALL

  The recall was initiated after Beckman Coulter confirmed an issue with the UniCel DxH 800 during in-house testing. It was determined that there is a potential for a false increase in platelet results, due to micro-bubbles. This situation could present a risk of falsely increased platelet results in patient samples as diluent containers are depleted.

• RECALL

  The recall was initiated because Beckman Coulter has confirmed an issue with the AutoMate Sample Processing Systems. If during the recovery from Error 81201001, a stuck sample carrier with a tube is moved backwards to the loading position, sample tube/input tray information will become mismatched for samples being loaded onto the AutoMate.

• RECALL

  The recall was initiated after Beckman Coulter confirmed reports of a new premature failure of the upper aspirate peristaltic pump in the systems listed above. Premature failure of the pump may negatively affect precision. The failure is limited to those UniCel DXI 800, DXI 600, and DxC 880i systems which have a pump identified with one of the new pump manufacturing numbers (Mfg. Nos.) listed ab
