In the study by Broman, IL-6 and CRP were the strongest predictors of severity in hospitalized patients with COVID-19 [11], while in another study, it was shown that abnormal levels of neutrophil to lymphocyte ratio (NLR), LDH, d-dimers, CRP, fibrinogen, and ferritin can be identified early on admission COVID-19 and can predict the severity of the disease [12]. This evidence concerns the gene CRP and COVID-19.
