Panels, Test, Susceptibility, Antimicrobial
Antimicrobial Susceptibility Test Panels (product code LTT) are microbiology devices used to determine the susceptibility or resistance of bacterial isolates to a range of antimicrobial agents, guiding appropriate antibiotic therapy. Regulated under 21 CFR 866.1640, they are classified as a Class 2 device requiring a 510(k) premarket notification to demonstrate substantial equivalence before marketing. The device is eligible for third-party review and falls under the Microbiology specialty. It is not flagged as an implant or life-sustaining device.
