ABSTRACT
Present pandemic scenario, there exists an unmet global need for the development of a rapid and sensitive method for the detection of SARS-CoV-2 infection. The available options for identification of SARS-CoV-2 infection are detection of viral RNA by qRT-PCR, Antigen or Antibody testing by serological methods. Even though many kits available commercially but none of them are rapid, sensitive and high throughput. OnCovid total antibody assay is a diagnostic method developed by us uses the principle of bio-layer Interferometry to detect IgM, IgA and IgG antibodies against SARS-CoV-2 antigens. This method overcomes many of the limitations normally faced in antibody detection by other methods and offers a superior platform for a rapid, sensitive and specific detection of SARS-CoV-2 infection. The test is economical, and the results can be obtained in as short as 30 seconds per test. In addition to its standalone use in early diagnosis of SARS-CoV-2, OnCovid total antibody assay can be used to therapeutic monitoring of antiviral therapies used in clinical management and to estimate the antibody titers during convalescent plasma donation.
