Differences between PC100 platelet counter and reference methods in measuring whole blood platelet count. The platelet count was determined using the PC100 platelet counter vs. the Sysmex® XP-300 (a,b) and the PC100 platelet counter vs. the Sysmex® XN-9000 (c,d). a,c Bland Altman plot visualizing the difference (%) between PC100 platelet counter and Sysmex® XP-300 or Sysmex® XN-9000. The grey lines represent the zero-difference line and the bold blue lines represents the median differences. b,d Passing-Bablok regression line is shown between the PC100 platelet counter and the reference methods. The grey line indicates the y = x line and the bold red line represents the regression line. N = 102
