Pemeriksaan ini biasa disebut dengan Electro Chemiluminescence Immunoasssay (ECLIA). ECLIA akan mendeteksi, mengikat, serta mengukur antibodi netralisasi. Sebagai informasi, antibodi netralisasi adalah antibodi yang dapat berikatan spesifik pada bagian struktur protein spike SARS-CoV-2. Protein spike adalah protein berbentuk paku yang tersebar The Roche Elecsys ® Anti SARS-CoV-2 (“Elecsys” in short form) assay, our reference assasy, uses a recombinant protein representing the nucleocapsid (N) antigen for the determination of IgG IgG was measured in survivors who had recovered from COVID‐19 1 year previously. Anti‐SARS‐CoV‐2 IgG persistence and titer depend on COVID‐19 severity. The highest virus‐specific IgG titers were observed in survivors with severe COVID‐19. Most asymptomatic carriers were negative for anti‐SARS‐CoV‐2 IgG. 1. Stieber et al. reported an LFIA detection device using fluorescent nanoparticles as a signal for antibodies against SARS-CoV-2, showing 100% specificity and sensitivity by qualitative detection of the IgM, IgA, and IgG antibodies against SARS-CoV-2 (Stieber et al., 2020). The results of this study need further independent evaluation, but if Aside from measuring IgG levels to various SARS-CoV-2 antigens (RBD, S1, and NP), an important component of our orthogonal approach is the inclusion of a surrogate neutralization assay which can be executed in an ELISA format with commonly available reagents in 1 d to 2 d, as opposed to using a live or pseudotyped virus . Using this surrogate a The total anti-SARS-CoV-2 IgM and IgG level of confirmed COVID-19 patients from the first to 12th week after symptom onset. Horizontal lines in the boxplots represent the median, the lower, and H0k4.
