On (b)(6)-2020, a customer from united states notified biomérieux of a qcv detected failure at positon b1 in association with the vidas® analyzer (ref.99735, serial (b)(4)).The customer stated the most recent passing qcv test was completed on (b)(6) 2020.A retrospective analysis was performed for the impacted time frame.Ten (10) procalcitonin (pct) samples from separate patients were tested in positon b1 between (b)(6) 2020 and(b)(6) 2020.Seven (7) samples were repeated, three (3) samples were not repeated.One (1) sample was initially underestimated for pct.There is no indication or report from the laboratory that the discrepant results led to any adverse event related to any patient's state of health.A biomérieux field service engineer (fse) visited the customer site and found the pump at position b1 was clogged.The fse performed a pump cleaner then performed a leak test and qcv test; both tests passed.Biomérieux will initiate an internal investigation.

This report was initially submitted following notification from a customer in the united states regarding a qcv detected failure at positon b1 in association with the vidas® analyzer (ref.99735, serial (b)(6)).Control c1 did not pass on position b1.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 system risk analysis.A biomérieux field service engineer (fse) visited the customer site and found the pump at position b1 was clogged and that the seals were dirty on all positions.The fse performed a pump cleaner and replaced all the seals.A leak test and qcv test was then performed; both tests passed.Conclusion: the cause of the qcv alert and of the failure of the control c1 in position b1 was a clogging of section b position 1.After a pump clean on the entire section, b1 passed all tests.
