The investigation determined that a higher than expected crea result was obtained from the non vitros mas qc fluid lot r1908 level when compared to qc package insert (pi) value.Although a definitive assignable cause was not identified, an unknown sample contaminant, specific to that cup/fluid event, is the likely assignable cause as the issue was specific to a single cup.In addition, pre analytical sample mix up cannot be ruled out as a contributing factor to the event.There was no indication that the vitros 5600 integrated system, or the vitros reagent lot in use malfunctioned.

The customer observed a higher than expected creatinine (crea) result from a non-vitros quality control (qc) fluid processed using a vitros 5600 integrated chemistry system.Thermo fisher mas qc fluid, level 1, lot r1908 result 262 umol/l versus the expected pack insert mean 86.6 umol/l.Biased results of the direction and magnitude observed may lead to inappropriate physician action if patient samples were affected.There was no allegation of patient harm as a result of this event.(b)(4).
