  1. Accuracy of the LISA-TRACKER was measured using 3 human serum matrix spiked with known levels of biosimilar (ABP501-Batch1 or ABP501-Batch2), 3 levels spanning the dynamic range: 1, 4 and 12 µg/ml. Quantification with LISA-TRACKER adalimumab assay and the percentages of recovery were calculated for the ABP501 batch1 and the ABP501 batch2. All the quantifications were established by LISA-TRACKER adalimumab assay
  2. Acceptance criteria: 80% < N < 120%
