Following customer complaints about amplification performance issues with home brew pcr and rt- pcr assays, biomérieux investigation has confirmed an issue with specific batches of magnetic silica (ref: 280133). the investigation concluded that downstream applications were impacted when the extraction volume was higher than 400µl and for double stranded nucleic acids target. double stranded nucleic acid applications with small (< 40kbp) and medium genome sizes (< to 1200 kbp) i.E., dna viruses are more impacted than higher human genomic dna and bacterial applications (> to 1200kbp).This may result in false negative, invalid or under-quantification of results. if invalid results are obtained, it could lead to a delayed result until a new run or a new extraction is performed.

bioMérieux is advising users to ensure controls with the same nature/structure as the target and/or external controls are used to detect the issue. Users are advised to reduce the sample input volume to 200µL, until the silica problems is resolved. Downstream ARGENE and NucliSENS easyQ HIV 1 V2.0 applications performed according to the IFU are not affected. It is recommended that the continued use with blood transfusion testing with confirmed by the Laboratory Director, and to discuss any concerns regarding previously reported results with the Laboratory Director.
