## Indications for use
The Acuitas® AMR Gene Panel, performed on the QIAGEN® EZ1® Advanced XL System and the OpGen Qualified QuantStudio™ 5 Real-Time PCR System, is a qualitative nucleic acid-based multiplex in vitro diagnostic test for detection and differentiation of antibiotic resistance markers to one or more antimicrobial agents. The test utilizes real‐time polymerase chain reaction (PCR) and is performed on isolated colonies of Pseudomonas aeruginosa, Enterococcus faecalis, or members of Enterobacterales grown in pure culture on blood agar or MacConkey agar. Organism identification results must be available prior to reporting results for the Acuitas AMR Gene Panel. Antimicrobial resistance gene results are reported by the Acuitas AMR Gene Panel for the combinations of bacterial pathogens and associated genetic resistance markers indicated in Table 1 below. The Acuitas AMR Gene Panel includes assays for the detection and reporting of genetic resistance markers associated with resistance to select drugs in the following antibiotic groups: aminoglycosides, carbapenems, cephalosporins, fluoroquinolones, penicillins, sulfonamides, trimethoprim, and vancomycin, to aid in the identification of potentially antimicrobial-resistant organisms. The panel includes an assay for the detection of the mobilized colistin genetic determinant MCR-1, a marker of public health importance associated with reduced inhibitory activity of polymyxins. The results of the Acuitas AMR Gene Panel for detection and identification of genetic determinants associated with antimicrobial resistance are used along with the Acuitas AMR Gene Panel Electronic User Guide (EUG). In certain cases, this information may be used as an aid to clinicians in the management of patients with known or suspected antibiotic non-susceptible or resistant bacterial infections. The EUG contains information on the appropriateness of reporting resistance markers detected by the Acuitas AMR Gene Panel for claimed organisms based on the strength of the collective, totality of scientific evidence delineating the level of association between molecular marker detection with phenotypic, clinical resistance. Test results are not conclusive or prescriptive for labeled use of any specific antimicrobial drug product, and therefore, this test cannot be used in place of or to postpone or delay phenotypic antimicrobial susceptibility testing. A “Detected” or “Not Detected” result does not rule out the presence of other antimicrobial resistance markers not detected by the Acuitas AMR Gene Panel. A "Not Detected" result for a genetic marker of antimicrobial resistance does not indicate susceptibility to associated antimicrobial drugs or drug classes, as multiple mechanisms of resistance may exist.
