Significant differences were also identified in several laboratory findings; lymphocyte ratio (LYMR), eosinophil ratio (EOSR), monocyte ratio (MONOR), total bilirubin (TBIL), total protein (TP), albumin (ALB), Ca, and URIC were all significantly lower in the severe COVID-19 group, while neutrophil ratio (NEUTR), FIB, aspartate transaminase (AST), glucose (GlU), and HsCRP were all significantly higher. Here, ALB is linked to COVID-19.
