K921658 is an FDA 510(k) clearance for the ANTI-DSDNA ANTIBODY TEST. Classified as Anti-dna Antibody, Antigen And Control (product code LSW), Class II - Special Controls.

Submitted by Immco Diagnostics, Inc. (Buffalo, US). The FDA issued a Cleared decision on March 22, 1993 after a review of 349 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Immunology FDA review panel, regulated under 21 CFR 866.5100 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Immunology review framework, consistent with the majority of Class II 510(k) submissions.
