K171566 is an FDA 510(k) clearance for the Atellica IM High-Sensitivity Troponin I (TNIH). Classified as Immunoassay Method, Troponin Subunit (product code MMI), Class II - Special Controls.

Submitted by Siemens Healthcare Diagnostics, Inc. (Tarrytown, US). The FDA issued a Cleared decision on July 19, 2018 after a review of 415 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1215 - 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: 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 Chemistry submissions.
