I have done an Antibody IgM ELISA test for my mom and dad after both doses of vaccination and after they recovered from COVID 19, but the test results show no antibodies. Can you please explain the report interpretation and is there anything to worry about?

IgM appears early and fades quickly. After recovery and full vaccination, the presence of IgG is more important. If no antibodies are found, immunity may still exist via T cells. No need to worry unless immunocompromised.

I recovered from Covid on May 2 and was tested positive on April 15. Should I get vaccinated now or should I wait for a few weeks? I took an antibody test last week and no antibodies were found in my report.

Hello Doctor. I faced coronavirus symptoms and did not go for any test, but now I have fully recovered. After 4 weeks, I took an antibody test by Thyrocare. My IgG antibody level is 1.89 and total antibody level is 4.34. I want to ask if the level of antibodies is low and will I be safe from future coronavirus infections? My second question is when should I go for the vaccine? I have also attached my test report. Please have a look.

My daughter received her COVID antibody test report today, which shows IgG is 2.62 and total antibodies (ELISA) is 0.36. She was previously infected with COVID and tested negative in October 2020. Should she get vaccinated now, or wait for some time? Does she have sufficient antibodies?
