K950838 is an FDA 510(k) clearance for the VIRAZYME CULTURE CONFIRMATION SCREEN FOR INFLUENZA AND PARAINFLUENZA VIRUSES. Classified as Antigens, Ha (including Ha Control), Influenza Virus A, B, C (product code GNT), Class I - General Controls.

Submitted by Zymetx, Inc. (Oklahoma City, US). The FDA issued a Cleared decision on June 17, 1996 after a review of 479 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.3330 - the FDA microbiology 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: 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 Microbiology submissions.
