This report was initially submitted following notification from a customer in the united states regarding underestimated results when testing an external quality control sample using their vidas® 3 instrument (ref.414356, serial number (b)(6) and vidas® d dimer exclus ii 60t us test kit ( ref.30455-01).The lot number for the assay was not provided.A biomérieux internal investigation has been completed with the following results: the customer was not able to provide any additional information and they could not confirm the lot number.Therefore, biomérieux chose nine (9) batches to analyze.All plasmas tested during the activity were within expected standards.According to the analysis of the quality data, no anomalies were identified during the manufacturing, control and packaging stages.A total of (b)(4) lots of control cards were analyzed and were within the expected standards and in the same trend for two (2) internal serum samples targeted at around 500 ng / ml.The cards tested were ones within expiry during the customer contact date and within expiry for one year from the customer contact date.There was no test carried out at the complaints laboratory because there was no specific lot identified by the customer and no customer sample was returned.The vidas® d dimer exclus ii batches analyzed were within the expected specifications.
