Biomerieux sent an Urgent Field Safety Notice dated January 2017, to Laboratory Manager or Laboratory Director. The Notice indicated what actions to take and included a reply form to be returned. Required actions: The following recommendations require your immediate attention to ensure the product will continue to perform per its labeled performance specifications, within its revised shelf-life of twelve (12) months. Product with NO remaining shelf life (after reduction): Identify impacted lots of ETEST Ceftriaxone TXL32 (Ref. 412302, 412303) (lots listed in Table 1 below) which are now expired after shelf-life reduction. Immediately order the replacement products appropriate for your institution. Until replacement product is available Laboratories may continue to use their now expired strips with the following recommendations: Laboratories should continue to follow their current QC procedures for ETEST Ceftriaxone TXL32 (Ref. 412302, 412303) for the lots listed in Table 1 in accordance with CLIA and local regulatory requirements, with a modification to increase the frequency of QC testing to weekly or every day of use if previous QC testing exceeds one week. Laboratories should include in the QC testing the strain N. gonorrhoeae ATCC 49226 (Expected range-MIC: 0.004-0.016 g/mL) defined as the stability indicator for ETEST Ceftriaxone TXL32 (Ref. 412302, 412303). The MIC result for this specific strain must fall in the acceptable range to confirm the validity of the QC test and performance of the ETEST with the clinical isolate. Only report results if all QC is in the acceptable ranges. When replacement product is received, discontinue using and discard impacted ETEST Ceftriaxone TXL32 (Ref. 412302, 412303) (listed in Table 1).
