510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.
Factor Xiii A, S, Antigen, Antiserum, Control
Immunology
This is an immunological reagent kit for detecting Factor XIII subunits (A and S), the transglutaminase that cross-links fibrin to stabilize blood clots, including antigen, antiserum, and control components for clinical laboratory immunoassays. Factor XIII deficiency is associated with impaired wound healing and excessive bleeding. It is classified as FDA Class 1, the lowest risk category, subject to general controls only. The product code is DBT, regulated under 21 CFR 866.5330, within the Immunology 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.
