Is it necessary to reanalyze a plate with VPF (Volume Precision Factor) that was already processed using a QIAcuity instrument that was purchased in 2020?

If you had analyzed your nanoplates without VFP, the impact depends on the variation of the partition volume of the new nanoplate batch compared to the latest. The VPF reduces the CV from approximately 5% to 2%. We recommend to re-analyze results in case the data originated from different wells (e.g., copy number variations or gene expression data sets for which the reference sample was measured in a different well). Results obtained across different plates should also be re-analyzed. A re-analysis is not required for assay data that were analyzed within the same well (e.g., mutation rate determination using two channels within the same well).
