Significantly, higher values of inflammatory biomarkers, such as white blood cells (12,546 ± 1077 vs. 10,655 ± 988, p = 0.001), C-reactive protein (CRP) (92.64 ± 13.36 vs. 74.36 ± 12.01, p = 0.002), erythrocyte sedimentation rate (ESR) (42.74 ± 4.03 vs. 33.89 ± 10.23, p = 0.001), and serum ferritin (453 ± 87.13 vs. 389 ± 27.44, p = 0.025) were observed in COVID-19-positive patients. Here, CRP is linked to COVID-19.
