Recall Z-1305-2026— Fujirebio Diagnostics, Inc.
Class II · Ongoing
Class II FDA medical device recall by Fujirebio Diagnostics, Inc., initiated 2025-12-11. It names one FDA 510(k) clearance: K242706. Product: Product Name: Lumipulse G ¿-Amyloid 1-42-N Plasma Immunoreaction Cartridges Model/Catalog Number: 235447 Software Version: Not Applicable Product Description: Lumipulse G ¿-Amyloid 1-42-N Plasma Immunoreaction Cartridges (IRC): Lumipulse G ¿-Amyloid 1-42-N Plasma is an assay system, including a set of immunoassay reagents (Lumipulse G ¿-Amyloid 1-42-N Plasma IRC), for the quantitative measurement of ¿-Amyloid 1-42 in K2EDTA plasma specimens based on chemiluminescent enzyme immunoassay (CLEIA) technology13 by a specific two-step immunoassay method on the LUMIPULSE G System. Lumipulse G ¿-Amyloid 1-42-N Plasma Immunoreaction Cartridges (IRC): 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-¿-amyloid 1-42 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-¿-amyloid 1-42 monoclonal antibodies (mouse) conjugate), 3. Assay Specific Solution: (Contains detergents in 50 mM MES buffer) Component: Yes. 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)..

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).
