K955895 is an FDA 510(k) clearance for the E. HISTOLYTICA TEST. Classified as Antigen, Id, Ha, Cep, Entamoeba Histolytica & Rel. Spp. (product code KHW), Class II - Special Controls.

Submitted by Techlab, Inc. (Blacksburg, US). The FDA issued a Cleared decision on August 30, 1996 after a review of 248 days — an extended review cycle.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.3220 — 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. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Microbiology review framework, consistent with the majority of Class II 510(k) submissions.
