Are there limitations to the COVID-19 antibody tests? Careers. Some T cells are programmed to remember the virus so they can respond quickly if they come across it again. These tests are typically done with blood samples in a research laboratory, though they can be done in clinical settings too. It remains particularly unclear how long antibodies exist in a persons body following a COVID-19 infection and how many antibodies are needed to neutralize SARS-CoV-2 following another exposure.
