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 0445U only for Elecsys® Phospho–Tau (181P) CSF (pTau181) and β–Amyloid (1–42) CSF II (Abeta 42) Ratio from Roche Diagnostics Operations Inc. The test uses cerebrospinal fluid for an electrochemiluminescent immunoassay (ECLIA) that generates a pTau181/Abeta42 ratio value, which may help the provider diagnose a patient with signs of cognitive impairment.
