Nettet13. aug. 2024 · In the scientific community, there has been broad discussion for years about how to calculate a robust cut point (CP) that accounts for biological and technical variability ( 3 – 5 ). The discussion is flanked by the FDA guidelines ( 2) that require justification for data excluded by outlier testing. NettetResults: Nonspecific signal measured in drug-naive samples used to determine assay cut points was uniformly low and close to the screening cut point. Confirmatory assays performed on incurred study samples with nonspecific responses significantly above the level observed during cut point determination resulted in incorrect ADA classifications.
