Voltage Gated Calcium Channel (Vgcc) Antibody Assay
Immunology
The Voltage Gated Calcium Channel (VGCC) Antibody Assay is an immunology in vitro diagnostic device intended for the semi-quantitative determination of VGCC antibodies in human serum; VGCC antibodies may be present in patients diagnosed with Lambert-Eaton Myasthenic Syndrome (LEMS), and results are to be used in conjunction with other clinical, electrodiagnostic, and laboratory findings. It is classified as Class 2 (FDA Class 2), requiring 510(k) premarket clearance, and is eligible for third-party review. The product code is PAF, with regulation number 866.5660 under the Immunology medical 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.
