How strong is your Covid immunity? A blood test could offer some insight

A newly developed blood test that measures the activation of T cells in the body could help doctors gauge how much immunity a person has against Covid-19.

A newly developed blood test that measures a specific immune response in the body could help doctors gauge how much protection a person has against Covid-19, according to a new study.

The test, which focuses on the part of the immune system that confers long-term protection by prompting the body to "remember" the virus, could help make sense of the complex tangle of Covid immunity that now exists from person to person.

The test can, for instance, measure immunity regardless of whether someone has developed a level of protection from one or more natural infections or from vaccinations and booster shots. Others, who may have much lower levels of protection because they are immunocompromised, could also use the test to assess their vulnerability and see how they responded to the vaccines, said Ernesto Guccione, an associate professor of oncological sciences and pharmacological sciences at the Tisch Cancer Institute at Mount Sinai.

"Ideally, it will give you a full picture of where you stand and a comprehensive picture of your immune protection," said Guccione, one of the authors of the study published Monday in the journal Nature Biotechnology.

The researchers said they are focused next on clinical trials in order to gain approval from both the Food and Drug Administration and the European Medicines Agency.
