Manufacturer Narrative
|
The customer did not provide patient demographics such as age, date of birth, sex, and weight.Initial the customer's telephone number is (b)(4).A beckman coulter (bec) field service engineer (fse) was dispatched to the customer's site to assess the instrument's performance.The fse checked the reagent pipettor and performed alignment; no hardware malfunctions were identified that may have caused, or contributed, to this event.The implicated reagent pack was discarded by the customer, so was not available for investigation.Investigation of the event determined that an error occurred on the manufacturer's reagent pack fill line.Due to the error, partially filled reagent packs were released for use.When used to analyze patient samples, partially filled reagent packs could cause erroneous results.In conclusion, the cause of the erroneously low access cea results is due to an error on the manufacturer's reagent pack fill line.(b)(4).All related mdr reports: mdr 2122870-2015-00564, mdr 2122870-2015-00571, mdr 2122870-2015-00572, mdr 2122870-2015-00573, mdr 2122870-2015-00574, mdr 2122870-2015-00575, mdr 2122870-2015-00576.
