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

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 positives.

They are included in the recall only because the calibrators are lot matched to the impacted reagent pack.

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

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.
