K110212 is an FDA 510(k) clearance for the INRATIO2 PI/NR MONITORING SYSTEM. Classified as Test, Time, Prothrombin (product code GJS), Class II - Special Controls.

Submitted by Alere San Diego, Inc (Formally Biosite Incorporate (San Diego, US). The FDA issued a Cleared decision on May 1, 2012 after a review of 462 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Hematology FDA review panel, regulated under 21 CFR 864.7750 - 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.
