Ortho Clinical Diagnostics (QuidelOrtho) confirmed certain Proboscis/Piston Assemblies manufactured between 07-Apr-2022 (Date code: 040722) and 19-Dec-2022 (Date code: 121922) may not perform as intended due to an out-of-specification barrel component. This may cause VITROS VersaTips and/or VITROS MicroTips to be improperly seated on the proboscis, which may result in falsely elevated Gentamicin and Valproic Acid assay results as well as an increased frequency of condition codes resulting in delayed patient results. The issue was identified by internal testing when reported instruments failed to pass release testing and were traced to the molded Proboscis part J56639 with date codes from 040722 onward.
