Table 3 Mean, standard deviation and bias of Accutrend Plus and GEM

From: Capillary and venous lactate measurements with a handheld device compared to venous blood-gas analysis for emergency patients

  GEM 0 - ≤2 GEM > 2 - ≤3.5 Total
  Mean SD Bias Mean SD Bias Mean SD Bias
Accutrend Plus
 Capillary 2.18 0.86 0.77 3.29 0.93 0.47 2.55 1.51 0.72
 Venous 2.27 0.60 0.86 3.70 0.74 0.88 2.71 1.48 0.88
GEM
 Venous 1.41 0.34 2.82 0.72 1.83 1.37
  1. Data are presented as mean, standard deviation (SD) and bias for values were GEM is between 0 and 2, 2–3.5 as well as Total. Bias = mean difference between AP lactate levels and GEM
