K141575 is an FDA 510(k) clearance for the PLAC TEST FOR LP-PLA2 ACTIVITY. Classified as Test, System, Immunoassay, Lipoprotein-associated Phospholipase A2 (product code NOE), Class II - Special Controls.

Submitted by Diadexus, Inc. (Redwood Shores, US). The FDA issued a Cleared decision on December 15, 2014 after a review of 186 days - an extended review cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 866.5600 - 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.

Device Classification

Product Code NOE Test, System, Immunoassay, Lipoprotein-associated Phospholipase A2
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.5600
Definition The Lipoprotein-associated Phospholipase A2, Immunoassay, System, Test, Is Intended To Measure Lipoprotein-associated Phospholipase A2 In Human Plasma In Conjunction With Clinical Evaluation And Other Patient Risk Factors Including Biochemical Analyses As An Aid In Predicting Risk For Coronary Heat Disease. This Device Differs From The Classification Regulation In That It Is A Different Analyte, Thus A New Marker For Predicting Risk Of Coronary Heart Disease. This Device Is Measuring An Enzyme That Is Produced By Macrophages Where As The Regulation Is For The Measurement Of A Lipoprotein.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Chemistry devices follow this clearance model.
