Web15 nov. 2024 · An antinuclear antibody (ANA) test looks for ANA in your blood. ANAs are a type of antibody called an autoantibody. Like other antibodies, they are produced by the immune system. While healthy antibodies protect the body from pathogens like viruses and bacteria, autoantibodies cause disease by mistakenly attacking healthy cells and tissues. Web25 apr. 2024 · For this test, we use a specific type of cell called HEp-2. ANA pattern refers to the distribution of staining produced by autoantibodies reacting with antigens in these cells.
