A customer in (b)(6) contacted biomerieux to report a discrepant organism identification in association with the vitek gram-negative (gn) identification (id) test kit.Vitek gn id result - staphylococcus hominis.Bruker mass spec (maldi-tof) - staphylococcus saprophyticus.It is not known which, if either, result was reported to the treating physician.However, there is no indication or report from the hospital or treating physician to biomerieux that the discrepant result led to any adverse event related to the patient's state of health.Culture submittal was requested by biomerieux for internal investigation.Strains were destroyed by the customer and are therefore not available for submittal.An internal biomerieux investigation will be initiated.

Internal biomérieux investigation was conducted.The customer did not comply with biomérieux's request for sample submittal.The customer provided one (1) vitek® 2 gp id lab report.The gp id lab report was reviewed for atypical reactions for staphylococcus saprophyticus.The atypical negative reactions present on the report indicate that the mcfarland density used was too light, the organism could have been too old or a non-recommended media was used.Since the strain was not submitted for testing, it is not possible to determine the cause of the misidentification.Evaluation of the manufacturing qc records indicates gp lot 242358010 passed on initial qc performance testing.There were no issues observed.The gp id card lot is performing in accordance with specifications.
