cord-316670-x9x54fxw	Flinck, Heini	Comparison of two fully automated tests detecting antibodies against nucleocapsid N and spike S1/S2 proteins in COVID-19	2020-08-29		.txt	text/plain	1869	108	52	Based on our results, the SARS-CoV-2 antibodies can be quite reliable detected 2 weeks after NAAT positivity and 3 weeks after the symptom onset with both tests. In this paper, we compared the performance of the fully automated Elecsys ® Anti-SARS-CoV-2 test detecting antibodies against nucleocapsid N protein and LIAISON ® SARS-CoV-2 S1/S2 IgG test detecting antibodies against spike protein S1-and S2-antigens. N protein based tests may be more sensitive to detect past COVID-19, but S protein may be a possible target for neutralizing antibodies, and SARS-CoV-2 antibodies against that antigen may better predict the protective immunity (Walls et al. In this study, we compared the performance of the fully automated Elecsys ® Anti-SARS-CoV-2 test detecting antibodies against nucleocapsid N protein and LIAISON ® SARS-CoV-2 S1/S2 IgG test detecting antibodies against spike protein S1-and S2-antigens.
