The aim of this study was to determine if sodium-citrate plasma is a suitable substitute for serum for cardiac troponin I (cTnI) measurement using the Beckman ACCESS 2 immunoassay. Linear regression analysis of cTnI levels in paired serum and sodium-citrate plasma samples from 80 patients provided a y-intercept of -0.0193 and a slope of 1.044. The correlation was good [r=0.995; 95% confidence interval 1.017 to 1.068, p <0.0001]. The paired results were not significantly different by Student's t… CONTINUE READING
