K943983 is an FDA 510(k) clearance for the IL TEST DIGOXIN & IL TEST DIGOXIN CALIBRATORS. Classified as Enzyme Immunoassay, Digoxin (product code KXT), Class II - Special Controls.

Submitted by Instrumentation Laboratory CO (Lexington, US). The FDA issued a Cleared decision on April 10, 1995 after a review of 307 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Toxicology FDA review panel, regulated under 21 CFR 862.3320 - the FDA toxicology 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 Toxicology review framework, consistent with the majority of Class II 510(k) submissions.
