A customer in italy notified biomérieux of obtaining irregular growth of candida albicans when testing clinical samples with the chromid® candida agar plate (ref.43631, lot 1007462580).In response to the customer complaint biomérieux conducted an internal investigation, which included testing of retained agar, analysis of returned agar, and a review of production records.Note: the customer did not submit the impacted strain for investigation therefore confirmatory testing of the isolate could not be performed.The following results were obtained: the retains of lots 1007462580 and 1007562620 were tested with atcc® organisms including candida albicans; all results were within specification one kit of returned plates was also tested for all quality control strains including candida albicans atcc® 2091 and candida alibicans atcc® 10231; all organisms tested obtained in-specification results.Review of the manufacturing batch records indicated that the impacted lot complied with specifications and neither non-conformances nor deviations were recorded.The error obtained by the customer was not reproduced.The chromid® candida agar plate package insert states: "growth depends on the requirements of each individual microorganism.It is therefore possible that certain yeast strains which have specific requirements (substrate, temperature, incubation conditions, etc.) may not develop or may not produce color." therefore, it is possible the impacted strain has specific growth requirements.However, as the impacted strains were not available for the investigation, it was not possible to verify this hypothesis.The investigation concluded chromid® candida agar plate lot 1007462580 is performing within specifications.
