The linearity of the kit was assayed by testing samples spiked with appropriate concentration of PREX1 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.Sample1:21:41:81:16serum(n=5)85-105%85-95%85-102%85-104%EDTA plasma(n=5)87-100%82-96%84-95%83-96%heparin plasma(n=5)86-100%85-99%86-96%82-97%
