An extractable nuclear antigen (ENA) panel is a blood test that detects autoantibodies in the blood that react with proteins in the cell nucleus. ENA panel typically consists of a group of four or six autoantibody tests. ENA panel testing is used to distinguish and monitor different autoimmune disease progression. In addition, it may be used as follow-up testing to a positive antinuclear antibody (ANA) test to help diagnose an autoimmune disorder.
