  1. WBC white blood cell; RBC red blood cell; HGB hemoglobin; HCT hematocrit value; MCV mean corpuscular volume; MCH mean corpuscular hemoglobin; RDW red blood cell volume distribution width; PLT platelet; NE# and NE% neutrophil count and percentage; LY# and LY% lymphocyte count and percentage; MO# and MO% monocyte count and percentage; MN-V-NE, MN-V-LY, and MN-V-MO mean volume of neutrophils, lymphocytes, and monocytes; SD-V-NE, SD-V-LY, and SD-V-MO standard deviation of neutrophil, lymphocyte, and monocyte volume; MN-C-NE, MN-C-LY, and MN-C-MO mean conductivity of neutrophils, lymphocytes, and monocytes; SD-C-NE, SD-C-LY, and SD-C-MO standard deviation of neutrophil, lymphocyte, and monocyte conductivity. Normally distributed data are expressed as mean ± standard deviation; non-normal variables are presented as median (interquartile range). Paired-sample t-test was used for normally distributed data, and Wilcoxon signed-rank test was used for non-normally distributed data. *p < 0.05; **p < 0.01; ***p < 0.001.
