Table 5.

Sensitivity, working range, and intra- and interrun accuracy and precision of the IL-13 assay under acidic conditions. Inter- and intrarun accuracy and precision were determined based on five levels of QCs ranging from the LLOQ to the ULOQ, assessed over six runs and five preparations per run.
