CRP and Hyperglycemia: All immunological biomarkers (ferritin, LDH, CRP, procalcitonin, IL-6, and CRP/ALB), coagulation biomarkers (aPTT, D-dimer, fibrinogen, PT, and INR), and hyperglycemia biomarkers (random glucose and HbA1c) were significantly higher in the severe patients compared to the other severity groups (Table 4).
