(b)(4).Device evaluation by manufacturer: on 25-apr-2018, a field service engineer (fse) visited the customer to address the reported event.During evaluation, the fse cleaned the white plastic block that the lower y-axis guide bar fits into.They also cleaned the upper and lower y guide rods and lubricated it with tri-flow.They adjust the y1-smp parameter 10 steps, and were able to run 3 full racks of patient samples.The needle was observed to be piercing the middle of the tube.The instrument was verified as operational.There was no further action required by fse.A (b)(4) complaint history review and service history review for similar complaints was performed for serial number (b)(4) from (b)(6) 2017 through aware date (b)(6) 2018.There were no similar complaints found during this time.The g8 operator's manual under chapter 5 maintenance procedures, 5.10 sampling needle replacement has a caution that states the following: replace the sampling needle if it is bent or broken.Use the following procedure to replace the sampling needle.Access to the inside of the analyzer is needed to replace the sampling needle.Be sure that only personnel who have been trained by tosoh or its representatives perform these operations.Be sure to wear protective clothing (goggles, gloves, mask, etc.) and take sufficient care to prevent infection during handling.Take care not to touch the end of the sampling needle during handling.If the needle placement is clearly off center of the primary tube, it must be adjusted.Cancel the assay and contact technical support.The most probable cause of the bent sample needle was due to dirt present in the white block that the lower y-guide rod passes through.

On (b)(6) 2018, a customer reported that the sample needle was bent on the g8 instrument.They stated that they did not have a replacement sample needle.Technical support specialists sent the customer a replacement sample to install.However, when they installed the new probe, it bent on the first sample.The customer stated that they observed that when the probe came down, it hit the side of the tube.A field service engineer (fse) was dispatched to address the reported event, which resulted in delay of results for hemoglobin a1c (hba1c).There is no indication of any patient intervention or adverse health consequences due to the delay in reporting of patient results.
