CRP and COVID-19: The maximum levels of C-reactive protein (CRP) and procalcitonin among COVID-19 cases and non-COVID-19 cases were not significantly different (p = 0.125 and p = 0.086), but the levels of CRP ≥ 300 mg/L and procalcitonin ≥ 5 ng/mL are significantly higher in control group (p = 0.05 and p < 0.001).
