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

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