Most people in the United States have some degree of immune protection against COVID-19, either from vaccination, infection, or a combination of the two. But, just how much protection does any individual person have?
MIT researchers have now developed an easy-to-use test that may be able to answer that question. Their test, which uses the same type of “lateral flow” technology as most rapid antigen tests for COVID-19, measures the level of neutralizing antibodies that target the SARS-CoV-2 virus in a blood sample.
Researchers have filed for a patent on the technology and are now hoping to partner with a diagnostic company that could manufacture the devices and seek FDA approval.
The test is designed so that different viral spike proteins can be swapped in, allowing it to be modified to detect immunity against any existing or future variant of SARS-CoV-2, the researchers say.
