Multiplex Immunoassay For Measles Virus, Mumps Virus, Rubella And Varicella Zoster Virus
Microbiology
The Multiplex Immunoassay For Measles Virus, Mumps Virus, Rubella And Varicella Zoster Virus (product code OPL) is a Class 2 in vitro diagnostic device regulated under 21 CFR 866.3510 in the Microbiology specialty (MI), cleared via 510(k). It is intended for the qualitative detection of IgG antibodies to measles virus, mumps virus, rubella, and varicella zoster virus (VZV) in human serum or plasma, to aid in assessing a patient's serological immune status; it is not intended for screening blood or plasma donors. The device is eligible for third-party review and is not an implant or life-sustaining device.

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.
