Summary:
Roche Diagnostics India launched its Quantitative antibody test- Elecsys Anti SARS CoV-2 S in January this year. Roche Elecsys Anti SARS CoV-2 S test measures antibodies that could help detect a past natural infection or body’s immune response to the vaccine. Roche Elecsys SARS CoV-2 S quantitative antibody test detects and quantifies antibodies in serum or plasma against the spike protein present on the surface of SARS CoV-2 virus. The Roche Elecsys SARS CoV-2 S correlates extremely well with tests that detect such neutralization activity. The right antibody test to assess immune response after COVID-19 vaccination would be the one that quantifies antibodies and shows a close correlation with neutralization tests, indicating development of a relevant immune response..
