Additional Manufacturer Narrative
The investigation determined that a higher than expected vitros nt pro-bnp ii result was obtained from a single patient sample when using vitros immunodiagnostics products nt pro-bnp ii reagent lot 0440 in combination with a vitros 5600 integrated system.A definitive assignable cause could not be determined with the information provided.Based on historical quality control results, a vitros lot 0440 performance issue is not a likely contributor to the event.However, it cannot be completely ruled out as the discordant result was generated on an expired reagent lot.An instrument related performance issue did not likely contribute to the event as the customer gave no indication of any instrument malfunction as all other tests predicted as expected.It was not possible to establish if the customer is following the sample collection device manufacturer¿s recommended centrifugation protocol; therefore, pre-analytical sample processing cannot be ruled out as a contributing factor.It is possible that cellular debris, due to poor sample preparation, was present in the affected sample, although this could not be confirmed.Additionally, the presence of an unknown sample specific interferent cannot be ruled out as contributing to the event.Continual tracking and trending of complaints has not identified any signals that would point to a potential systemic issue with vitros nt pro-bnp ii, lot 0440.
