The COVID-19 diagnostic test performances of the biochemical blood values that were significant in the comparison analyzes of the discharge and Ex group were tested with ROC analysis. In the literature, an AUC of 0.5 suggests no discrimination (i.e., ability to diagnose patients with and without the disease or condition based on the test), 0.7 to 0.8 is considered acceptable, 0.8 to 0.9 is considered excellent, and more than 0.9 is considered outstanding (15, 16). Accordingly, among the “area under the ROC Curve (AUC)” values, Urea (AUC=0.868), LDH (AUC=0.849), Albumin (AUC=0.863) and CRP(AUC=0.874) values can be considered excellent. The highest significant AUC value was obtained for CRP (AUC=0.874) (Table 3).
