The Ana and ENA tests are blood tests that help diagnose autoimmune diseases. They are used to detect antibodies in the blood that are associated with specific autoimmune disorders. Autoimmune diseases are conditions in which the body's immune system mistakenly attacks healthy tissues in the body.
ANA Test
The ANA test, or Antinuclear Antibody Test, is used to detect antibodies to the body's own cells and tissues. These antibodies can indicate an autoimmune disorder or other conditions in which the immune system is attacking the body's own tissues. The ANA test looks for antibodies that are directed against components of the nucleus, which is the center of each cell.
ENA Test
The ENA test, or Enzyme-Linked Immunoassay Test, is used to detect antibodies to specific proteins, enzymes, and other molecules in the body. These antibodies can indicate an autoimmune disorder or other conditions in which the immune system is attacking the body's own tissues. The ENA test looks for antibodies that are directed against specific proteins, enzymes, and other molecules.
Both the ANA and ENA tests are used together to diagnose autoimmune disorders. They can also help to determine which specific autoimmune disorder is present. If the results of both tests are positive, further tests may be needed to confirm the diagnosis.
