K892393 is an FDA 510(k) clearance for the ACID PHOSPHATASE REAGENT. Classified as Acid Phosphatase, Naphthyl Phosphate (product code CKB), Class II - Special Controls.

Submitted by Medical Analysis Systems, Inc. (Camarillo, US). The FDA issued a Cleared decision on July 20, 1989 after a review of 104 days - within the typical 510(k) review window.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1020 - 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: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.
