NettetDynamic range is the minimum and maximum sample amount that can be processed through an assay system, while still producing accurate and precise results. An assay system is the complete workflow from sample to results. Real-Time PCR instruments can support a large dynamic range. NettetMoreover, the assay exhibited high sensitivity with a limit of detection (LOD) of 0.176 ng/mL and a limit of quantification (LOQ) of 0.8 ng/mL. Furthermore, the intra-assay precision and inter-assay precision values were 5.29– 7.10% and 9.41%– 13.66%, respectively. It is also noteworthy that the test results deviated by less than ± 10% ...

Nettet29. des. 2024 · The precision (intra-assay, inter-assay and reproducibility) was estimated by the coefficient of variation (CV) of calibrators and drinking water proficiency samples. Matrix effect is the influence of the components of a sample other than the analyte of interest in the measurement (Zhong et al. 2011). NettetThe intra- and inter-assay, inter-operator and inter-instrument acceptance criteria was that precision should be comparable to that of the initial validation performed at Comparative Method Lab (≤7%CV). 6.4 Training and transfer. Owing to the limited sample stability and the complexity of the assay, on-site training was required.
