Due to a risk of false positive results that could lead to unnecessary medical treatment.

Due to incorrect calibrations and controls, their is a potential of incorrect reporting of lower %IS and molecular response values.

APLS IgM reagent kits were packaged with the incorrect conjugate, which could lead to an increase in false-positive and false-negative results.

Bio-Rad received four customer complaints from 11/30/2022 to 12/21/2022 on BioPlex 2200 Anti-CCP Kit (Lot 301481) stating that results were discrepant while performing lot-to-lot validation against previous lots. Internal testing at Bio-Rad has demonstrated that Lot No. 301481 exhibits a specificity of 94.5% (95% CI 91.8  96.4) whereas the IFU indicates a specificity of 97.8% (95% CI 96.1  98.8%). The reduction in specificity may lead to an increase in the number of false positivesBio-Rad received four customer complaints from 11/30/2022 to 12/21/2022 on BioPlex 2200 Anti-CCP Kit (Lot 301481) stating that results were discrepant while performing lot-to-lot validation against previous lots.

Due to an unusual increase in the positivity rate with human IgM antibodies to cytomegalovirus (CMV) Enzyme Immunoassay (EIA).

The problem is with the Bio-Rad VARIANT nbs Sickle Cell Program Resin Update CD-ROM software; Model Number: 250-3020, included in VARIANT nbs Sickle Cell Progam Reorder Pack #250-3000. This CD-ROM software included in specific lots of VARIANT nbs Sickle Cell Progam Reorder Pack causes all customized settings in the Setup/Test/Data Setup subscreen and Setup/Test/Pattern Setting subscreen to be overwritten with the default settings when the Update Kit procedure is performed.The VARIANTnbs Sickle Cell Program has been validated using the default Resin Update CD¿ROM parameters for the intended use. However, there is a risk that the customer's custom pattern settings may be different than the default settings, resulting in a different pattern being assigned to some samples that the laboratory has validated. Following the complaints from 4 customers who experienced these issues, the firm initiated this recall.

Performance concerns for the CMV IgM analyte. Analyte has demonstrated variable elevated background depending on the handling of the reagent pack.

Due to current concerns related to COVID-19 vaccine interference with the RPR portion of the BioPlex 2200 Syphilis Total & RPR panel, as well as intermittent manufacturing challenges to produce RPR reagents that consistently meet stability specifications

Due to two issues: 1) Customer complaints associated with greater than expected Rapid Plasma Reagin (RPR) reactivity which does not confirm with treponemal antibody test which may be due to a positive correlation between the mass COVID vaccinations and false reactive RPR results, and 2) During routine stability monitoring, an increase in mean bias above specification was observed which can cause elevated RPR reactivity potentially due to early shelf-life failure.

A new lot of ANA screen control and any subsequent control lots are incompatible with older lot numbers of ANA calibrators and ANA reagent packs.

The increased level of RPR reactivity in the BioPlex 2200 Syphilis Total & RPR kit material number 12000650.

User-induced circumstances can contribute to the EVOLIS Microplate Processor System not handling repeat testing requests/results properly and may contribute to transmitting erroneous results to the customer's Laboratory Information System (LIS).

Abnormal coloration of agar plates and the growth of non-characteristic MRSA colonies.

Abnormal coloration of agar plates and the growth of non-characteristic MRSA colonies.

The connector of the power supply was capable of fitting other components provided with the system. However, the voltage output of the reader power supply is incompatible with the other component and, if incorrectly connected, could result in irreparable damage to the system.

The error "Washer Reagent Clean Fluid" level low alarmed, which prompted the customer to open the system drawer. When the system drawer was opened the customer noted the plate transport was still running and as a consequence the plate was pushed off the plate transporter.

On a rare occasion, there is a potential to assign a patient result to an incorrect sample ID when running in D10 Rack Loader configuration.

The spare component Anti-HBs Cutoff Calibrator, Catalog number 26154, is recalled because the expiration date of 2016-04-30 printed on label in error.

There is an issue with the buffers which impacts the quantification of the Hemoglobin F peak. Calibration and Quality control are likely to fail if the affected lots are used.

On a rare occasion the D-10 software might generate an extra result by duplicating the result form the previous sample and the Sample ID/Injection number from the next sample.

D-10 A1c Dual Program Floppy was programmed incorrectly and cartridge injections counts are not being updated correctly when switching between the D-10 Dual Short Program and Extended Program on the D-10 Hemoglobin Testing System.

The FSE Image Upgrade kit (part 92019C) is recalled due to issue related to the export of data from the EVOLIS analyzer to Laboratory Information Systems (LIS) when using the MONOLISA Anti-HBs EIA Quantitative Determination in EVOLIS APF version 6.0.

The Liquichek" ToRCH Plus IgM Control - Positive, contains detectable levels of HCV RNA which originated from the non-specific human IgM component used in the mouse monoclonal antibody conjugation process for this product.

Prolonged exposure of the MONOLISA Anti-HBs EIA Conjugate Diluent component to light may result in elevated Optical Densities (OD) in some samples such that a negative sample could elevate to a grey zone or low positive result.
