Customer complaints were received regarding falsely elevated results for some patient samples. Internal studies with customer return samples confirmed potential interactions that may lead to falsely elevated results when processed as below on the same instrument: " ARCHITECT Syphilis TP (LN 8D06) and/or ARCHITECT AdviseDx SARS-CoV-2-IgG II (LN 6S60) precedes ARCHITECT Anti-HCV testing (LN 1L79). " Alinity i Syphilis TP (LN 07P60) precedes Alinity i Anti-HCV testing (LN 08P05).

Abbott identified that samples tested for ARCHITECT STAT High Sensitive Troponin I and STAT High Sensitivity Troponin I assays (LN 3P25 and LN 2R98) may show interaction when processed directly after the ARCHITECT iGentamicin (LN 1P31) assay and patient results might be impacted.

Abbott has identified that Calibrator lot 08219BE00 is potentially impacted by an increase in Relative Light Units (RLUs) up to 94%. It has been confirmed that the increase in the calibrator RLU values may cause a decrease in the control values and patient results. Patient values generated using the impacted calibrator lot 08219BE00 may have changed interpretation from reactive to falsely non reactive. Results impacted may present as a (falsely) non reactive result that fall in the range between 0.50 to 0.99 S/CO.

Potential reliability issue with the Alinity ci series Level Sensor, Bulk Solution. The development of environmental stress on the bulk solution level sensor can cause cracks.

Abbott internal studies have determined that atmospheric Carbon Dioxide (CO2) can be absorbed into the Alinity c Carbon Dioxide reagent, resulting in the potential for incorrect results. Abbott was made aware of this issue from customer complaints. Internal testing demonstrated that the amount of CO2 absorbed is higher with increased reagent carousel rotation and when the volume of reagent in the cartridge is reduced. This phenomenon can be detected as a shift in QC. The shift is predictive in both direction and magnitude of the potential impact to patient results.

Abbott has identified an issue with the Alinity i Gear Pump Assembly (part number A 30108552 01) resulting in foaming/bubbling out of the bottle reservoir for Concentrated Wash Buffer and an unexpected amount of dried residue of buffer. The foaming/bubbling is a result of an improper calibration of the pump s operating speed.

The safety interlock covering the septum piercing probes within the bulk solution bottle holder may not deploy when a bulk solution bottle is removed from the Alinity ci series and Alinity s System.
