Manufacturer Narrative
|
The investigation determined that a lower than expected patient result was obtained for vitros phyt microslides processed using a vitros 5600 integrated system.There was no indication of a vitros 5600 instrument malfunction or a vitros phyt reagent issue.The event was isolated to one patient sample.The most likely cause of the event is a sample related issue due to the observation of debris floating in the sample as well as high turbidity and hemolysis.Per the vitros phyt instructions for use: do not use hemolyzed samples.It is suspected that the sample quality impacted the vitros 5600 system sample metering event causing the low phyt outlier result, although this could not be definitively proven.

Event Description
|
The customer obtained a lower than expected phenytoin (phyt) patient result (6.46 ¿g/ml versus expected 16.96 ¿g/ml) using vitros phyt microslides on a vitros 5600 integrated system.Biased results of the magnitude and direction observed may lead to inappropriate physician action if they were to occur undetected.The lower than expected phyt result was obtained from a patient sample while evaluating the assay as part of the installation of the vitros 5600 system.The vitros 5600 system was not yet being used by the customer for routine testing.There was no allegation of patient harm as a result of this event.(b)(4).
