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.
Test, Thrombin Time
Hematology
The Test, Thrombin Time (product code GJA) is a hematology coagulation assay that measures the time for clot formation after addition of thrombin to plasma, assessing the conversion of fibrinogen to fibrin and used to detect fibrinogen deficiencies, dysfibrinogenemia, and the presence of heparin or thrombin inhibitors. This device is classified as FDA Class 2, indicating moderate risk, and requires 510(k) premarket notification. Regulated under 21 CFR 864.7875 in the Hematology specialty (HE), it is eligible for third-party review.

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.
