Plazomicin Test System, Immunoassay
Clinical Toxicology
The Plazomicin Test System, Immunoassay is an in vitro diagnostic device intended to measure plazomicin levels in human specimens, with measurements used to monitor drug levels and ensure appropriate therapy in patients being treated for complicated urinary tract infection. It is classified as FDA Class 2, requiring 510(k) premarket notification, and is eligible for third-party review, under regulation 862.3460 in the Clinical Toxicology specialty.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
