Manufacturer Narrative

An industry customer in singapore notified biomérieux of obtaining misidentification results in association with the api® listeria test (ref.(b)(4), lot 1008452670).Review of the batch records for api listeria (ref.(b)(4); lot# 1008452670, 1008988000 and 1008506770), did not highlight any anomalies during manufacturing or quality control which could lead to an identification issue.There is neither trend of complaints on the batches 1008452670, 1008988000 and 1008506770, nor on product reference (b)(4) regarding the issue reported.The quality control strains tested (listeria monocytogenes atcc® 19115¿ and atcc® 7644¿) on the retained sample of the batch impacted (batch 1008988000) complied with specifications.The customer confirmed ((b)(6) 2022) that this issue was not reproduced during retesting at their laboratory with the atcc® 7644¿ strain, using batch 1008988000.The biomérieux complaint investigation laboratory was also unable to determine or confirm a root cause for this customer¿s issue.Biomérieux customer service reminded the customer of the lab protocol for misidentification or no identification issues with api listeria and/or difficulties to interpret: - check the purity of the strains tested before carrying out any identification with api listeria strips, - perform the tests with fresh strains (24 hours), - follow strictly the protocol described on the instruction for use, - respect the validated delay of storage of reagents after opening, - follow the recommendations in the iso 11133 standard regarding the conservation, preparation and subculture of collection strains (such as atcc strains).
