A high recovery of Iron assay has been observed at some customer sites. Internal studies confirmed the positive shift of Quality Control and patient samples results, up to 15% for Iron Products (Alinity c Iron Reagent REF. 08P3920) to be used on Abbott Alinity Instrument and to 30% for Iron Products (IRON REF. 6K95-41 and IRON REF. 6K95- 30) to be used on Abbott Architect Instrument. When using the affected lots, there is a potential for delay in reporting patient results due to QC failure, also a potential for falsely elevated results.

Reagent 1 component may result in Quality Control values shifting out of acceptable range, which is not resolved by recalibration.

Results for ammonia are below the linear range of the assay for samples that have been collected in sodium or lithium heparin tubes.

Calibrator vials were incorrectly labeled. Use of incorrectly labeled vials will cause the instrument to generate a warning that calibrators are incorrectly loaded and calibration will not be completed successfully.

Claim for stability after reconstitution from lyophilized to liquid form does not meet the requirements. New IFU instructions for handling the product provided to end users.

Added an additional SmartWash parameter for the Lithium and Alinity c Lithium Reagent Kit, catalogue number 8L25-30 and 08P5320 to prevent the potential for carryover from the ARCHITECT Lactate Dehydrogenase (LDH) reagent (LN 2P56) may result infalsely elevated lithium patient results
