K853224 is an FDA 510(k) clearance for the PHASE II B-12/FOLATE KIT. Classified as Radioassay, Vitamin B12 (product code CDD), Class II - Special Controls.

Submitted by Medical & Scientific Designs, Inc. (Rockland, US). The FDA issued a Cleared decision on October 3, 1985 after a review of 63 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1810 - the FDA in vitro diagnostics and chemistry 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.
