Biomérieux internal investigation was conducted.The results in the gp id card showed the strain was positive for only the (b)(4) well in the gp id card and all other tests/reactions were negative.Propionobacterium acnes is an anaerobic species.Anaerobic species are not claimed in the vitek® 2 gp id knowledge base, and should be tested in the vitek® 2 anc id card.In addition, the gram stain of propionobacterium acnes shows pleomorphic, branching gram positive bacilli resembling corynebacteria (also claimed by the anc id card and not the gp id card).The customer chose the incorrect card to test the strain.Based on the behavior and characteristics of the strain, selection of the vitek® 2 gp id was inappropriate and constitutes off-label use.The investigation concluded that the vitek® 2 gp id test kit did not malfunction and is performing as intended in accordance with product specifications.
