Due to manufacturing issue (incorrectly processing) with in vitro multidrug resistant test.

Due to a manufacturing issue - missing a drug in well 4/4 but contain double the amount of antibiotics

Due to the likely presence of contamination in well(s).

Sample preparation system designed to automate staining, lysing, cell washing has a software error that causes samples to be dispensed close to or touching tube bottoms, which could dislodge fluid line, result in sample loss, spillage, make instrument inoperable and will lead to unintentional removal of 60-100 microliters from final sample, may lead to incorrect diagnosis or patient management.

Due to specific lots of diluents contributing to elevated platelet Daily Checks background counts cycle with use with analyzers.

Beckman Coulter has determined that, due to a potential communication issue, the analyzers listed above may not successfully restart following a standard shutdown, even after multiple attempts. If this issue occurs, the instrument will be unable to complete initialization and transition to Ready mode and the instrument will not process patient samples, QCs or calibrators. This causes delayed results.

It has been determined that certain lots of Access 2 Reaction Vessels may contain manufacturing deformities. The bottom (round end) of the Reaction Vessel may have a small protrusion or hair like deformity. This could cause causing instrument errors (e.g., pipetting, rake, wash carousel errors) that could delay patient results.

Due to a software error code that crashes during acquisition on patient sample when running customer defined acquisition protocol. This may lead to delayed patient results.

Beckman Coulter has identified that there is an increased probability Synchron Systems Direct LDL Cholesterol (LDLD REF 969706) reagent lot M404166 may generate false high results. The issue was discovered internally and confirmed on August 19, 2025 by Beckman Coulter.

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.

Automated pipetting, diluting and specimen processing workstations for flow cytometric analysis device instructions for use list incorrect dead volumes: Cassette Type/List volume/correct volume, B/750/1582 microliters, and E/1300/2093 microliters. Device software does not rock Cassette E, used with 15mmX92mm Sarstedt tubes. May lead to incorrect diagnosis or error in patient management/treatment.

Beckman Coulter has confirmed a software anomaly on DxI 9000 Access Immunoassay Analyzer and the DxC 500i Clinical Analyzer that may prevent correct application of user-specified manual dilution factors when ordering additional tests for samples already "In Progress" using the same "Sample ID number". This can lead to false low or high patient results and potential delays in reporting, risking erroneous diagnoses if undetected.

Specific SYNCHRON Systems Modular Chemistry Phosphorus (PHOSm REF 467868) reagent lots may fail calibration before the lot expiration date which causes a delay in obtaining patient results.

On a clinical analyzer, when ordering a Clinical Chemistry (CC) combination test simultaneously with an Immunoassay (IA) test, if the IA test is processed between the CC tests, CC sample status will remain In Progress with no errors, may cause processing delays.

Hematology analyzers configured with HGB photometers may result in erroneously high hemoglobin (HGB) results on samples with elevated white blood cell (WBC) counts.

Access Thyroglobulin reagent lot 439163 may generate erroneously high patient results. Falsely increased Access Thyroglobulin results may lead a physician to pursue unnecessary diagnostic imaging studies and/or inappropriate therapy adjustments in patients being monitored for residual or recurrent thyroid cancer.

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.

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.

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.
