CRP and COVID-19: Increased D-dimer and CRP have been consistently reported in severe cases of COVID-19 infection [10], and are linked to the increased inflammation and coagulopathy in patients with COVID-19; a D-dimer >3mg/L FEU in COVID-19 patients has been previously associated with an increased risk of a thromboembolic event despite the use of prophylactic anticoagulation [11], which might also be tightly linked to microthrombosis of the pulmonary vasculature, but its use as a single predictor is limited [12].
