Manufacturer Narrative

Patient demographics such as weight, race and ethnicity were not supplied.A beckman coulter (bec) field service engineer (fse) was dispatched to assess the instrument's performance.The fse inspected the instrument's analytical module and removed and cleaned the wash wheel.Additionally, the sample probe was replaced as it appeared to be "slightly bent".Other proactive measures were taken to ensure instrument reliability including replacing the wash wheel bearings, the ejector plate sensor and the mixer motor.Lastly, the wash tower was cleaned and alignments adjusted/verified.The instrument's performance was verified through system check, hs (high sensitivity) system check, precision testing and carryover testing.All verification testing passed within published performance specifications.The fse did not note any hardware issues which would have contributed to this incident.The root cause of the low reproductive results (access inhibin a, access total bhcg ((5th is), access ue3 and access afp)) could not be determined with the information supplied.
