Manufacturer Narrative

(b)(4).Device evaluation by manufacturer: on (b)(6) 2018, a field service engineer (fse) was dispatched to the customer's facility to address the reported issue.Fse found air was entering the sampling system, causing the reported issue.Fse cleaned the rheodyne valve, replaced the rotor seal, stator face assembly, the 3-way joint for the needle to the small syringe, and the tubing that goes to the small syringe.Fse then primed, calibrated, and ran quality controls (qc) and patient samples.All results were within acceptable range and the total areas were within the specific range of 500-4000.The g8 instrument is functioning as intended.No further actions required from field service.A 13-month complaint history review and service history review for (b)(4) from (b)(6) 2017 through aware date (b)(6) 2018 for similar complaints was performed.There was one (1) similar complaint identified during the searched period.The g8 operator's manual under chapter 1, introduction and application, under interpretation of results, provides guidance on the total area and chromatography.Paragraphs three to five state " results will not be reported if the total area (ta) is <500 which can be seen in severe anemia.Results will not be reported if the ta is >4000 which can be seen in polycythemia.(see "abnormal red cell survival in previous section).The optimal goal for total area is between 700-3000.However a ta in the range of 500-4000 is acceptable and reportable for whole blood specimens.The chromatogram must be examined for any unidentifiable peaks (i.E., p00, p01,) before the a0 peak.Do not report the result if these peaks exist.When there is a question concerning the chromatography, repeat the sample.If the repeated sample also displays unusual characteristics, it is appropriate to evaluate whether the unusual result is due to an abnormal sample, a procedural error, an instrument malfunction or a sample-handling problem.For further information, see the troubleshooting section in this operator's manual." in addition, chapter 3 assay operations, under detailed peak information, the optimal range for total area is 700 to 3000.The most probable cause of the reported event was due to air entering injection valve.

Event Description

On (b)(6) 2018, customer reported getting low total area (ta) flag (the acceptable range is 500-4000; optimal range is 700 to 3000) during quality controls (qc) on the g8 instrument.On (b)(6) 2018, a field service engineer (fse) was dispatched to address the reported event, which resulted in delay in reporting of patient results for hemoglobin a1c (hba1c).There was no indication of any patient intervention or adverse health consequences due to the delay in reporting of patient results.
