CRP and COVID-19: In addition to older age (>65 years), obesity, and male gender, predictors of COVID-19 mortality are high C-reactive protein (CRP) (>100 mg/L in fatal vs. 3 mg/L in non-fatal), raised ferritin (mean 1297 ng/mL in non-survivors vs. 614 ng/mL in survivors), increased white blood cell count, lymphopenia, and abnormal chest imaging [1,3,4].
