Pcr standard curve accuracy
Spletconsidered genuine outliers and may be dropped from the standard curve. For example, at 3 replicates per point, the one-sided P-score for alpha 0.05 (5%) is 0.941 (also see current USP). Only outliers confirmed to have tau-values >= 0.941 using the appropriate Dixon-Q calculation may be dropped from the standard curve best fit analysis. SpletIn the present study, we evaluated the co-infection using TaqMan SARS-CoV-2, Flu A/B, RSV RT-PCR multiplex assay by spiking with culture fluid of Influenza, SARS-CoV-2, and RSV controls and found 100% accuracy with the assays. The present method was concordant with the reference method to detect co-infection.
