To date, it has been suggested that laboratory values such as lymphocyte count, neutrophil-to-lymphocyte ratio (NLR), thrombocyte-lymphocyte ratio (PLR), C-reactive protein (CRP), ferritin, troponin, D-dimer could be proper in the evaluation of the risk of mortality and critical disease.[6,7] This has led to the search for a test that could show a specific prognosis of multisystem involvement in COVID-19. Here, CRP is linked to COVID-19.
