K023889 is an FDA 510(k) clearance for the WIENER LAB. CHAGATEST ELISA RECOMNINANTE V.3.0, MODEL 96 TESTS CAT. NR. 1203254. Classified as Enzyme Linked Immunosorbent Assay, T. Cruzi (product code MIU), Class I - General Controls.
Submitted by Wiener Laboratories Saic (Rosario, Santa Fe, AR). The FDA issued a Cleared decision on February 11, 2004 after a review of 447 days - an unusually long review period, suggesting complex equivalence evaluation.
This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.3870 - the FDA microbiology 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 Microbiology submissions.
