Event Description

A customer from canada alleged that seven slides (patient orders) appear to have been stained on the benchmark ultra with a different staining protocol than what was assigned on the slide label (barcode) and intended to be used.The result was reported out to the treating physician for one of these seven slides, however it was confirmed that the patient was not treated based on the incorrectly stained slide results.

Manufacturer Narrative

Throughout the investigation and considering the information and evidence collected, a product issue was not found.After extensive review of the data and communication with the customer, this issue appears to have been caused due to user error.Based on the investigation, the most likely scenario is that the operator opened the instrument's reagent hood to add the missing reagents and, while doing so, moved the slides that were on drawers (slide positions) 24-30 over to drawer 5-11 without opening the drawers.The operator took the 7 slides that the instrument already scanned slide labels on drawers 5-11 and replaced them with the 7 slides that failed to scan on drawers 24-30.This caused the 7 slides that failed to scan on drawers 24-30 to be stained using the protocols loaded onto the respective positions 5-11.To be detected, a slide must be loaded into the drawer correctly.A slide must be added (loaded) by opening and closing the slide drawer.Only then, will the newly added slide be detected when scanned by the instrument barcode reader to initiate the start of the staining run.Instruction is available in the user manual on how to load/unload slides on the benchmark ultra instrument.
