K931420 is an FDA 510(k) clearance for the COATEST(R) ANTITHROMBIN III, MODIFICATION. Classified as Antithrombin Iii Quantitation (product code JBQ), Class II - Special Controls.

Submitted by Kabi Pharmacia Hepar, Inc. (Franklin, US). The FDA issued a Cleared decision on May 2, 1994 after a review of 419 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Hematology FDA review panel, regulated under 21 CFR 864.7060 - the FDA hematology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Hematology submissions.
