Product Description
Product Name: Lumipulse G pTau 217 Plasma Immunoreaction Cartridges Model/Catalog Number: 81550 Software Version: Not Applicable Product Description: Lumipulse G pTau 217 Plasma Immunoreaction Cartridges (IRC): Lumipulse G pTau 217 Plasma is an assay system, including a set of immunoassay reagents (Lumipulse G pTau 217 Plasma IRC), for the quantitative measurement of pTau 217 in K2EDTA plasma specimens based on chemiluminescent enzyme immunoassay (CLEIA) technology by a specific two-step immunoassay method on the LUMIPULSE G System. 3 ¿ 14 Tests: 3 racks, 14 IRCs per rack, 1 test per IRC. Each IRC contains (abbreviated contents): 1. Antibody-Coated Particle Solution: (Contains anti-phosphorylated Tau (217) monoclonal antibody (mouse)-coated particles). This solution contains gelatin and turns into gel at 15¿C or lower, 2. Enzyme-Labeled Antibody Solution: (Contains alkaline phosphatase (ALP)-labeled anti-Tau monoclonal antibodies (mouse) conjugate), 3. Assay Specific Solution: (Contains chemical stabilizers in 50 mM Tris buffer) Component: Yes. Lumipulse G pTau217/B-Amyloid 1-42 Plasma Ratio
Reason for Recall
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).
