Plain-English summary
Abbott GmbH is recalling 5110 units of the Alinity i Anti-HCV Reagent Kit (List Number 08P0521, Lot Numbers 52020BE00, 54149BE00, 56384BE00, 58172BE00, 59203BE00) nationwide in the United States.
Abbott received customer complaints about falsely elevated results for some patient samples when testing was performed on the Alinity i instrument. The company conducted internal studies using returned samples and confirmed that a potential interaction occurs when certain tests are run immediately before the Anti-HCV test on the same instrument. Specifically, falsely elevated Anti-HCV results may occur when Alinity i Syphilis TP testing precedes Alinity i Anti-HCV testing. Similar interactions were also observed with ARCHITECT brand instruments when ARCHITECT Syphilis TP and/or ARCHITECT AdviseDx SARS-CoV-2-IgG II testing precedes ARCHITECT Anti-HCV testing.
Falsely elevated Anti-HCV results could lead patients and healthcare providers to believe a patient is positive for Hepatitis C antibodies when they are not. Healthcare facilities using affected lot numbers should review recent test results and consider retesting patients where syphilis or SARS-CoV-2-IgG testing immediately preceded Anti-HCV testing on the same instrument. Patients who received testing during the affected period should consult with their healthcare provider about whether retesting is warranted.
