K924370 is an FDA 510(k) clearance for the STACLOT(R) PNP TEST KIT. Classified as Test, Time, Partial Thromboplastin (product code GGW), Class II - Special Controls.

Submitted by American Bioproducts Co. (Parsippany, US). The FDA issued a Cleared decision on August 9, 1993 after a review of 346 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Hematology FDA review panel, regulated under 21 CFR 864.7925 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Hematology review framework, consistent with the majority of Class II 510(k) submissions.
