Intra-assay Precision (Precision within an assay):CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays):CV%<10%
Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
