The firm, Bio-Rad Laboratories, sent an "Voluntary Field Correction: BioPlex 2200 EBV IgG Calibrator Set, Lot# 46704 for EBV NA-1 Analyte" letter dated March 16, 2011 domestic customers via Fed-Ex and and to international subsidiaries via e-mail. The letter described the product, problem and actions to be taken. The consignees/customers were informed that Bio-Rad confirmed downward shift in control values for the EBV NA-1 analyte when using the BioPlex 2200 EBV IgG Calibrator Set, Lot # 46704. If this occurs, the customers were instructed to readjust the positive control mean using the procedure presented in the customer notification "BioPlex 2200 Quality Control Values (L60013402)". If the re-adjusted mean of the EBV NA-1 controls is within the manufacturer's limit, patient results may be reported. If the new assay positive control mean still does not fall within the manufacturer's limit, the customers were instructed to contact their local Bio-Rad Technical Support and do not report the EBV NA-1 values. The customers were also instructed to complete and return the CUSTOMER RESPONSE FORM via fax to 510-741-5775. If the BioPlex 2200 EBV VCA IgG and EBV EA-D IgG positive and negative control means are within the acceptable QC range, and subsequent passing QC runs are obtained, patient results may be reported for these analytes. Bio-Rad will be manufacturing a new lot of the BioPlex 2200 EBV IgG Calibrator Set which will bring the control values within the manufacturer's limit. It may be necessary to readjust the QC ranges after the consignees receive this new calibrator set lot. Bio-Rad will send their consignees/customers the replacement calibrators and calibrator CDs when available. The consignees/customers were also instructed to discard the calibrator set lot# 46704 in accordance with national and/or local regulations.
