K842243 is an FDA 510(k) clearance for the ALKALINE PHOSPHATASE ASSAY KIT. Classified as Nitrophenylphosphate, Alkaline Phosphatase Or Isoenzymes (product code CJE), Class II - Special Controls.

Submitted by Diagnostic Chemicals, Ltd. (Usa) (Canada, US). The FDA issued a Cleared decision on July 18, 1984 after a review of 43 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1050 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
