Comparison between FACSPresto and FACSCalibur. Passing-Bablok regression plot comparison of s absolute CD4 count and c CD4% values obtained from FACSPresto with the FACSCalibur as reference standard. The solid line represents the regression line and dashed line the 95% CI. Pollock plots indicating %mean bias between b absolute CD4 count and d CD4% values obtained on FACSPresto compared with those obtained on the FACSCalibur. The solid line represents the mean bias, the dashed line represents mean bias ± 1.96SD
