A customer in (b)(6) had contacted biomérieux to report the occurrence of a misidentification of campylobacter species as neisseria cinerea in association with the vitek® 2 neisseria-haemophilus (nh) identification (id) test kit.An internal biomérieux investigation was performed.The customer's strain and raw data were not available.The customer had incubated the isolate at 42c for 48 hours.The nh culture requirements table states the age of culture range is 18-24 hours for campylobacter isolates.Strains tested outside of the recommended culture requirements may give atypical results.The strain was identified by the customer lab as campylobacter species by gram stain morphology and positive campylobacter agglutination testing.One lab report was received.The lab report submitted had an 88% probability of neisseria cinerea with five atypical negative reactions ( odc, pvate, dmlt, lglm, dxyl) for an identification of campylobacter species.An increased number of atypical negative results can indicate a strain with decreased viability, user set up error or an atypical strain.Without the strain or raw data it is not possible to further evaluate the cause of the mis-identification.The vitek 2 nh id card, lot #2450433103, met final qc release criteria.The lot passed qc performance testing.
