A high level of anti-dsDNA in the blood is strongly associated with lupus and is often significantly increased during or just prior to a flare-up. When the anti-dsDNA is positive and the person tested has other clinical signs and symptoms associated with lupus, it means that the person tested likely has lupus.What is positive double stranded DNA?
A positive Double Stranded DNA Antibody Blood Test may indicate lupus in 50-70% of cases, if preceded by a positive antinuclear antibodies (ANA) blood test The laboratory test results are NOT to be interpreted as results of a "stand-alone" test.What is double stranded DNA antibody?
Anti-double stranded DNA antibody (anti-dsDNA) is one of a group of autoantibodies called antinuclear antibodies (ANA). Normally, antibodies protect against infection, but autoantibodies are produced when a person's immune system fails to adequately distinguish between "self" and "non-self."
