The 278 white blood cell (WBC) counts and respective WBC differential counts and neutrophil-to-lymphocyte ratio (NLR) corresponding to 119 COVID-19 patients; ‡ Mean ± Std. Deviation of WBC differential counts of 500 Mexican healthy blood donor volunteers [32,33,29]; ∗ Mean basophil count for healthy subjects was obtained, according to values established by Sysmex® [32,33,30].
