Antichromatin Antibody Test

Alternate Names

  • Anti-NCS (Antinucleosome Antibodies)
  • Anti-HST (Antihistone Antibody Test)

Autoimmune diseases cause the body to attack itself, which leads to inflammation and results in damage to muscles, tissues, and organs. The body produces antibodies specific to each autoimmune disease; the antibody levels measured in your blood are then used by your doctor to diagnose the disease that is causing your symptoms. Antichromatin antibody test is a blood test that is mainly used to diagnose SLE (systemic lupus erythmatosis). Two different antibodies are measured: antinucleosome antibodies and antihistone antibodies. Both of these blood tests help your doctor to diagnose SLE; and to rule out rheumatoid arthritis, dermatomyositis, and polymyositis as the cause of your symptoms.
