Furthermore, since the first phases of COVID-19may be similar to those of other viral diseases such as flu, Zhang et al. suggested a specific triage selection for patients with suspected COVID-19, including the analysis of laboratory parameters which usually increase in the early stages of viral infection, such as C-reactive protein and lactate dehydrogenase (LDH) values [15], without the evaluation of the clotting system. The gene discussed is CRP; the disease is influenza.
