A new, next-level coronavirus-antibody test that measures not just antibodies’ presence but also how much protection they afford are on the way. The test, which on Wednesday received emergency ...
An extractable nuclear antigen panel, or an ENA panel, tests for presence of autoantibodies in the blood that react with proteins in the cell nucleus. It is usually done as a follow-up to a positive antinuclear antibody test and when one is showing symptoms of an autoimmune disorder. The ANA tests for the presence or absence of autoantibodies ...
