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).
