VIRAL DETECTION
Coronaviruses can be detected by ELISA, Immunoflourescence test,
Immunoblot and PCR (Roos, 2003; Chan et al., 2004; Maschinen et al.,
2005; ECDC, 2020; WHO, 2020). For epidemiological purposes the virus
have to be cultured prior to other techniques in order to obtain good
results (WHO, 2003; Ren et al., 2004). However, cultural technique is
not recommended for COVID-19 (WHO, 2020). The main techniques currently
in use for both SARS-CoV and 2019-nCoV are the RT-PCR and ELISA (Leung
et al., 2004; Ren et al., 2004; CDC, 2020; Wu et al., 2020) . Analysis
of blood proteins has provided a helping tool for identification of
biomarkers for evaluation SARS-CoVs although they are not essential
diagnostics at point of care (Ren et al., 2004; Kang et al., 2005).
