K112910 is an FDA 510(k) clearance for the AP 72OS SEMI-AUTOMATED INSTRUMENT. Classified as System, Test, Radioallergosorbent (rast) Immunological (product code DHB), Class II - Special Controls.

Submitted by Hitachi Chemical Diagnostics, Inc. (Mountain View, US). The FDA issued a Cleared decision on December 20, 2012 after a review of 444 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Immunology FDA review panel, regulated under 21 CFR 866.5750 - the FDA immunology 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 Immunology submissions.
