Table 2. Laboratory findings at the admission of COVID-19 patients.

Data are presented as median (IQR) or N (%).

*p<0.05 was considered significant.

Laboratory values were collected at admission.

Student t-test and Mann-Whitney U test were applied.

AST: aspartate transaminase; ALT: alanine transaminase; SGOT: serum glutamic-oxaloacetic transaminase; SGPT: serum glutamic-pyruvic transaminase; APTT: activated partial thromboplastin time; PT: prothrombin time; INR: international normalized ratio; LDH: lactate dehydrogenase; CRP: C-reactive protein; WBC: white blood cell
