Technical Data:
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Human FGF23 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human FGF23 were tested on 3 different plates, 20 replicates in each plate.
