Detailed explanation-1: -Singapore claims first use of antibody test to track coronavirus infections | Science | AAAS.

Detailed explanation-2: -Antibody Test Results You cannot do the antibody test at home; hence, you need to go to any pathology lab in India. The test is only admissible if it is done in an ICMR approved pathology lab for COVID testing in India. Once it is complete, then you need to wait for the results.

Detailed explanation-3: -Currently available antibody tests for SARS-CoV-2 assess IgM and/or IgG to one of two viral proteins: S or N. Because COVID-19 vaccines are constructed to encode the spike protein or a portion of the spike protein, a positive test for S IgM and/or IgG could indicate prior infection and/or vaccination.

Detailed explanation-4: -Antibody serology tests check for the presence or level of specific antibodies in the blood. Antibodies are proteins that your immune system makes to fight foreign substances. These substances are often pathogens, (disease-causing germs) such as viruses and bacteria.

Detailed explanation-5: -The immune system produces these antibodies - proteins that are critical for fighting and clearing out the virus. If test results show that you have antibodies, it can mean that you have been infected with the COVID-19 virus in the past or you have antibodies after being vaccinated.
