Description

The Anti-dsDNA antibody test detects autoantibodies that specifically target double-stranded DNA (dsDNA) in the body. These antibodies are most commonly associated with Systemic Lupus Erythematosus (SLE), an autoimmune disease in which the immune system attacks the body’s own tissues.

Why the Anti-dsDNA Test Is Important

  • A positive anti-dsDNA test often indicates active lupus, particularly when the kidneys are involved (lupus nephritis).
  • It is considered a key marker for monitoring disease activity in patients with SLE.
  • Testing can help diagnose lupus, assess disease progression, and guide treatment decisions.
