ELISA-based antibody test developed by the National Institute of Virology, Pune, has a sensitivity of 92% and its specificity is 97%. The test involves drawing the blood of the person.

ELISA plate

The sample is then placed inside the small wells of an ELISA plate. These plates are coated with the antigen or the inactivated form of the virus.

colour change

If the blood contains antibodies, it binds to the antigen and a substrate solution is added to the well. The reaction usually produces a colour change, thus detecting antibodies.

form of a rapid test

ELISA tests can be done manually or in a semi-automatic and automatic way. ELISA is also a form of a rapid test. However, other rapid antibody test kits are point-of-care and use a finger-prick method to draw blood.

detect antibodies

They take much lesser time and do not need a laboratory process to detect antibodies. Those who test positive using these tests are usually tested with RT-PCR tests.
