Manufacturer Narrative

An investigation was initiated in response to a customer complaint of a qcv detected failure occurring at section e1 of the vidas® analyzer (ref.99735, serial number (b)(6)).A qcv failure is not an abnormal behavior.It means that the qcv played its role as a functional control.This control is meant to detect residual risks, that are rare and sudden.Those risks are already present and accepted into the vidas analyser additional information was obtained from the field service engineer (fse) that performed the on-site testing and maintenance.The fse performed a pump test for position e1 and the test failed.The fse reported that the pump channel for e1 was visibly clogged.The fse performed a pump cleaning on section e1, which cleared the clog and the instrument was returned to normal functionality.A final leak test was performed in order to quality the instrument and all values were within expected range.The initial report incorrectly stated that the affected position was a1.The correct information is that the affected position was e1.
