K120749 is an FDA 510(k) clearance for the HUMAN IGG CSF KIT. Classified as Method, Nephelometric, Immunoglobulins (g, A, M) (product code CFN), Class II - Special Controls.

Submitted by The Binding Site Group , Ltd. (Birmingham, GB). The FDA issued a Cleared decision on May 17, 2013 after a review of 431 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Immunology FDA review panel, regulated under 21 CFR 866.5510 - 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.
