K221900 is an FDA 510(k) clearance for the Stat Profile Prime Plus Analyzer System. Classified as Electrode Measurement, Blood-gases (pco2, Po2) And Blood Ph (product code CHL), Class II - Special Controls.

Submitted by Nova Biomedical Corporation (Walham, US). The FDA issued a Cleared decision on September 29, 2023 after a review of 456 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1120 - 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.
