Erratic results were reported from the user, the customer indicated the analyzer is old, and was seeking to buy a replacement.Through interviewing the user, it was noted the sensor connector had corrosion.Corrosion was noted on sensor pins.Corrosion of the sensor pins occurs when there is overexposure of the analyzer pins to the assay's acidic treatment reagent.This occurs when used test sensors are not removed immediately after testing (per instrument instructions) or when too much sample is added to the test sensor.Periodic testing with blood lead qc controls is used to monitor analyzer performance.No reported harm or injuries occurred as a result of this issue.(b)(4).
