精密度：
| Intra-assay Precision (Precision within an assay): CV%<8% | ||||||
| Three samples of known concentration were tested twenty times on one plate to assess. | ||||||
| Inter-assay Precision (Precision between assays): CV%<10% | ||||||
| Three samples of known concentration were tested in twenty assays to assess. | ||||||
线性度：
| To assess the linearity of the assay, samples were spiked with high concentrations of bovine SP-B in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. | ||||||
