K941993 is an FDA 510(k) clearance for the PHARMACIA CAP SYSTEM PHADIATOP FEIA. Classified as System, Test, Radioallergosorbent (rast) Immunological (product code DHB), Class II - Special Controls.

Submitted by Pharmacia, Inc. (Columbus, US). The FDA issued a Cleared decision on January 30, 1996 after a review of 645 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.
