Event or Problem Description

Additional Manufacturer Narrative
The investigation has determined that false positive anti-hbs (ahbs) results were obtained from two different patient samples and a non-vitros kangchesi tan qc negative quality control fluid using the vitros anti-hbs reagent lot 5070 on a vitros 3600 immunodiagnostic system.A definitive assignable cause of the event could not be determined.Based on historical qc results, a vitros ahbs lot 5070 performance issue is not a likely contributor leading up to the event.Additionally, there is also no indication of any instrument malfunction and unexpected instrument performance is not a likely contributor to the event.However, as diagnostic within run precision testing was not performed on the instrument, an instrument issue cannot be completely ruled out as contributing to the event.The most likely cause of the event is an unknown issue isolated to one vitros ahbs lot 5070 reagent pack (b)(6) in use at the time of the event.However, this is the second discordant pack of this nature identified at this site so a local handling or storage issue cannot be ruled out as contributing to this event.Continual tracking and trending of complaints has not identified any signals that would indicate a potential systematic issue with vitros ahbs reagent lot 5070.
