Comparison using Passing‐Bablok regression of platelet results from 120 patients without platelet clumps between magnesium sulfate and K2EDTA (A, B) and between sodium citrate and EDTA K2 (C, D) in fluorescence (A, C), and impedance (B, D) modes. Regression lines are presented with solid red lines, 95%CI lines are presented with dashed red lines, and identity lines are presented with solid grey lines. PL‐I, platelets measured on the XN analyser in impedance mode; PL‐F, platelets measured on the XN analyser in fluorescence mode; Citrate, sodium citrate; magnesium sulfate, MgSO₄.
