Lumipulse G pTau217/B-Amyloid 1-42 Plasma Ratio — Reason: Customers may experience inaccurate test results by observing a higher frequency of classification in the indeterminate and positive zone and/or low specificity when compared back to FDA-cleared CSF ratio/PET imaging, due to falsely elevated positive ratio or falsely elevated indeterminate ratio results causing an incorrect classification of a patient as having amyloid pathology associated with Alzheimer s disease (positive result) and/or requiring more clinical testing of that patient (indeterminate result). — Status: Ongoing
