Linearity

 

Matrix
 1:2 1:4 1:8 1:16
serum(n=5) 78-92% 85-96% 93-102% 95-104%
EDTA plasma(n=5) 86-97% 91-102% 81-97% 93-107%
Heparin plasma(n=5) 82-94% 83-96% 91-103% 82-99%

 

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of AREG and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Recovery

 

Matrix Recovery range Average
serum(n=5) 93-101% 97%
EDTA plasma(n=5) 85-103% 94%
Heparin plasma(n=5) 95-105% 100%

 

Matrices listed below were spiked with certain level of recombinant AREG and the recovery rates were calculated by comparing the measured value to the expected amount of AREG in samples.

Precision

 

Intra-assay Precision (Precision within an assay)：CV%<8%

Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-assay Precision (Precision between assays)：CV%<10%

Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
