There are four screening criteria: LOD < 3.0 ng/mL; LLOQ<2.0 ng/mL; Background<0.1; R2>0.990. Bold font represents the features that meet the standards. There are four assays that meet the requirements, taking into account the repeated consistency of the data. Finally, Assay 38 and Assay 43 were screened.
