Submitted by G.D. Searle and Co. (Mchenry, US). The FDA issued a Cleared decision on June 22, 1977 after a review of 62 days - a notably fast clearance cycle.

This device falls under the Immunology FDA review panel, regulated under 21 CFR 862.2320 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
