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

Serum(n=8) | 90-107 | 97 |
EDTA plasma(n=8) | 87-102 | 93 |
Cell culture media(n=8) | 84-97 | 91 |
Samples were spiked with high concentrations of Human β-EP and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
