Summary
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 0459U only for Elecsys® Total Tau CSF (tTau) and β–Amyloid (1–42) CSF II (Abeta 42) Ratio from Roche Diagnostics Operations Inc. The test uses cerebrospinal fluid for electrochemiluminescent immunoassay (ECLIA) tests that generate a tTau/Abeta42 ratio value, which may help the provider diagnose a patient with signs of cognitive impairment.
