What is anti-dsDNA?

Anti-dsDNA stands for antibodies against double-stranded DNA. These autoantibodies are formed when the immune system incorrectly reacts against the body's own genetic material, which is particularly common in SLE.

  • Autoantibody: Antibody that attacks the body's own structures
  • dsDNA: Double-stranded DNA – our genetic material
  • Anti-dsDNA: Immune reaction directed against the body's own DNA

Why analyze anti-dsDNA?

An anti-dsDNA test is analyzed primarily to:

  • Make a diagnosis of suspected SLE
  • Follow disease activity in people with SLE
  • Distinguish SLE from other autoimmune diseases
  • Identify the risk of kidney damage (lupus nephritis)

How are anti-dsDNA test results interpreted?

The sample is taken as a blood sample. The result can be negative, weakly positive or clearly positive. Sometimes a quantitative level is stated, e.g. IU/ml or kE/L depending on the analysis method.

Interpretation of test results:

Results Interpretation Comments
Negative No measurable anti-dsDNA antibodies Reduces the likelihood of SLE
Low positive Possible SLE or other autoimmune disease Does not necessarily indicate disease
High positive Strong suspicion of SLE Often linked to lupus nephritis (kidney disease)

Note: In order to make a diagnosis, a positive test is not enough; a comprehensive assessment of symptoms and other laboratory values ​​is also needed.

A positive anti-dsDNA test is not dangerous in itself, but it may be a sign of an underlying autoimmune disease that needs further investigation – especially systemic lupus erythematosus (SLE). However, treatment is not given based solely on the presence of anti-dsDNA, but only if you have a disease that requires it. In people with SLE, the level of anti-dsDNA antibodies can change over time and increase during relapses or decrease when the disease is in a quiet phase, which makes the marker also useful for follow-up.
