A field service engineer (fse) was at the customer site to address the reported issue.The fse confirmed the error on the error log and was able to reproduce the issue by processing a sample.The fse resolved the issue by flushing both the main and hybrid arm nozzles and adjusted the hybrid arm z-axis to the small bottle.Additionally, the fse adjusted the hybrid arm reagent cup tip lane, standard test cup, incubator bottom, and the main arm clog sensitivity.Instrument validation was performed by processing quality control (qc) and patient samples.Qc results passed within the customer ranges.The aia-2000 analyzer returned to operation.No further action required by field service.A complaint history review and service history review for similar complaints was performed for serial number (b)(4) from installation date of 11jul2019 to aware date (b)(6) 2019.No other similar complaints were identified during the search period.The aia-2000 operator's manual states the following: [2070] clogging detected during specimen suction by main arm.Cause: the negative pressure detected after specimen suction exceeded the standard.The specified amount of specimen may not have been obtained because the sampling nozzle was blocked.The measurement result will be flagged (sc flag).Solution: verify that the specimen is free of solid substances (such as fibrin) or that there is sufficient volume of specimen if it is prepared in the primary tube, and retry the measurement.If retry fails, contact tosoh service center or local representatives.The probable cause of the issue is attributed to clogged main and hybrid arm nozzles and misaligned z-axis to the small bottle.

A customer reported receiving error message 2070, clogging detected during specimen suction by main arm, while operating on the aia-2000 analyzer.The customer stated the error was intermittent and could not analyze a sample due to the error.As a result, the customer sent the sample out to a reference laboratory for analysis.The customer noted the error also occurred when processing controls.A field service engineer (fse) was dispatched to address the reported issue, which resulted in delayed reporting of intact parathyroid hormone (ipth) and follicle-stimulating hormone (fsh) patient results.There was no indication of patient intervention or adverse health consequences due to the delay in reporting.
