K951799 is an FDA 510(k) clearance for the VARICELLA-ZOSTER VIRUS DIRECT IMMUNOFLUORESCENCE ASSAY. Classified as Antiserum, Cf, Varicella-zoster (product code GQX), Class II - Special Controls.

Submitted by Light Diagnostics (Temecula, US). The FDA issued a Cleared decision on March 20, 1996 after a review of 336 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.3900 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Microbiology review framework, consistent with the majority of Class II 510(k) submissions.
