Event or Problem Description
A customer contacted the ortho clinical diagnostics (ortho) technical solution center (tsc) to report a non-reproducible, lower than expected sodium result was obtained from a non-vitros biorad quality control processed using vitros chemistry products sodium (na+) slides lot 4284-1165-3527 on a vitros xt 7600 integrated system.Biorad lot 92980 l2 result of <75 mmol/l vs an expected result of 158.9 mmol/l biased results of the magnitude and direction observed may lead to inappropriate physician action if they were to occur undetected on patient samples.The non-reproducible, lower than expected result was from a non-patient fluid and was not reported outside of the laboratory.However, the investigation cannot conclude that patient samples would not be affected if the event were to recur undetected.There has been no reported allegation of patient harm as a result of this event.This report corresponds to ortho clinical diagnostics inc (ortho) complaint number (b)(4) and reportability assessment (b)(4).
Additional Manufacturer Narrative
The investigation determined that a non-reproducible, lower than expected sodium result was obtained from a non-vitros biorad quality control processed using vitros chemistry products sodium (na+) slides lot 4284-1165-3527 on a vitros xt 7600 integrated system.The investigation could not determine a definitive assignable cause of the event.Based on historical quality control results, a vitros na+ lot 4284-1165-3527 performance issue is not a likely contributor of the event.However, an individual slide related issue could not be entirely ruled out.Continual tracking and trending of complaints has not identified any signals that would point to a potential systemic issue with vitros na+ lot 4284-1165-3527.An instrument related issue could not be entirely ruled out as a contributing factor of the event as diagnostic precision testing was not performed on the vitros xt 7600 integrated system.However, there was no evidence indicating that the instrument malfunctioned.An issue related to the biorad control is not likely a contributing factor of the event as an acceptable repeat result was obtained using the same control vial.
