Published: July 27, 2026Updated: August 25, 2026

Anti-dsDNA measures antibodies that target double-stranded DNA, which are often elevated in autoimmune conditions like systemic lupus erythematosus (SLE).

Anti-double-stranded DNA (anti-dsDNA) antibodies are a type of autoantibody that target the DNA within cells. These antibodies are highly specific for systemic lupus erythematosus (SLE), making them a critical biomarker for diagnosing and monitoring this condition.

Elevated levels of anti-dsDNA antibodies are typically associated with increased disease activity in SLE patients. Regular monitoring of these levels helps in assessing the effectiveness of treatment and predicting potential flares.

The presence of anti-dsDNA antibodies is not exclusive to SLE; they can also be found in other autoimmune disorders, albeit at lower levels. Therefore, interpreting anti-dsDNA results requires careful clinical correlation.

Frequently asked questions

What does a positive anti-dsDNA test mean?
A positive test indicates the presence of antibodies that target double-stranded DNA, which is strongly associated with SLE.
Can anti-dsDNA levels change over time?
Yes, anti-dsDNA levels can fluctuate with disease activity, making regular monitoring essential for managing SLE.
