K170463 is an FDA 510(k) clearance for the KetoSens Blood B-Ketone Monitoring System, KetoSens Multi Blood B-Ketone Moni.... Classified as Nitroprusside, Ketones (urinary, Non-quant.) (product code JIN), Class I - General Controls.

Submitted by I-Sens, Inc. (Seoul, KR). The FDA issued a Cleared decision on April 13, 2018 after a review of 422 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1435 - 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.
