Anti-Double Stranded DNA

Test information: Anti- (double stranded)-DNA antibodies are highly specific markers of SLE and autoimmune (lupoid) hepatitis. Raised levels are found in 50-70% of patients with active, particularly untreated, SLE. Some patients with SLE (40-60%) however, never develop anti-DNA antibodies. Performed after a positive ANA of > 1:160.
