On May 22, 2019 the firm issued the Product Recall letter along with a customer reply form to all customers informing them that the firm has identified that the calibrator level 2 may have been manufactured incorrectly for a portion of the lots and that although this lot may generate an active calibration curve, a shift to QC and patient results may occur. Between concentration range of 5.33% to 6.87% there is no impact to assay performance, however, outside of this range, a bias of greater than 3% may be seen with patient results. For US customers the Product Recall Letters were sent via FedEx Priority Overnight Express (note-for OUS, each country organization will establish their own method of notification, which consistence of mailings or customer visits). The Product Recall Letter instructed customers to: - Immediately discontinue use of the calibrator lot number and switch to the alternate calibrator lot. - Destroy any remaining inventory of impacted material according to customer's laboratory procedures. - Review this letter with Medical Director or Laboratory Management and follow laboratory protocol regarding the need for reviewing previously reported patient results. - Complete and return the Customer Reply Form. Contact your local firm representative for assistance with replacement product. - If customers have forwarded the product to other laboratories, please inform them of this Product Recall and provide them with a copy of this letter. - Please retain this letter for your laboratory records.
