Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Pentraxin 3, Long (PTX3) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Pentraxin 3, Long (PTX3) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%
Matrices listed below were spiked with certain level of recombinant Pentraxin 3, Long (PTX3) and the recovery rates were calculated by comparing the measured value to the expected amount of Pentraxin 3, Long (PTX3) in samples.
