This is a Proprietary Laboratory Analyses (PLA) code, meaning that the code applies to only one unique lab test made by a specific manufacturer or performed by a specific lab. Report 0412U only for PrecivityAD® blood test from C2N Diagnostics LLC. Using liquid chromatography with tandem mass spectrometry (LC–MS/MS), the test evaluates a plasma specimen for levels of beta amyloid 40 and 42, as well as identifying the patient’s apolipoprotein E (ApoE) protein phenotype (such as ApoE2 or ApoE4). An algorithmic analysis of the findings yields a probability score that the patient may have amyloid plaques indicative of Alzheimer’s disease (AD).
