Anti-double-stranded DNA (dsDNA) Patients with this antibody who do not have SLE usually have a similar illness, such as rheumatoid arthritis. Sometimes the test is positive in otherwise well family members of lupus patients.
What does a positive dsDNA mean?

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 considered a high anti-dsDNA?
Titer levels for anti-dsDNA antibodies were reported as negative (≤4 IU/ml), indeterminate (5–9 IU/ml), or positive (≥10 IU/ml).
Can anti-dsDNA become negative?
Regarding anti-dsDNA ± subjects, anti-dsDNA antibodies became negative after a mean period from the diagnosis of years.
What is a normal dsDNA level?
Interpretation: A NORMAL result is < 10 IU/mL (NEGATIVE). An EQUIVOCAL result is 10 – 15 IU/mL. A POSITIVE result is > 15 IU/mL The results obtained by this method should serve as an aid to diagnosis and should not be interpreted as diagnostic in itself.
What does dsDNA 1/10 mean?
