Internal investigation was conducted (ansm actinobaculum schaalii survey strain #657, lot 2).The organism was sub-cultured, and testing included: vitek® 2 anc id card.16s sequencing (reference method) to determine the intended result.Results: 16s sequencing confirmed the expected identification to species actinobaculum schaalii.Identification to species actinomyces meyeri was obtained by vitek® 2 anc id (with vitek 2 systems software version 6.01).Identification to species actinobaculum schaalii was obtained by vitek® 2 anc id (with vitek 2 systems software version 7.01).The misidentification to actinomyces meyeri was duplicated using the customer software version 6.01; actinobaculum shaalii is not claimed in the version 6.01 knowledge base.The vitek® 2 6.01 product information manual (ref.410791) indicates which organisms can be identified using the vitek® 2 anc id card; actinobaculum schaalii is not listed.Per the vitek® 2 product information manual, "testing of unclaimed species may result in an unidentified result or misidentification." for any organism placed into a test card, the vitek® 2 system will assess the card readings against the known organisms and provide an organism identification, if possible, based on a combination of growth well reactions.For results with a percent confidence of <99%, the customer must make a determination of acceptance or further testing based on the logical likelihood of the identification considering other laboratory and clinical factors.The vitek® 2 anc id card is performing as intended within the scope of product specifications.
