What are normal anti-dsDNA levels?

Explanation: A normal result is < 10 IU/mL (negative). EQUIVOCAL results in 10 – 15 IU/mL. Positive results > 15 IU/mL The results obtained with this method should be used as an aid to the diagnosis and should not be construed as a diagnosis in itself.

Is it normal to have anti-dsDNA?

Anti-double-stranded DNA antibodies (anti-dsDNA) are a specific type of ANA antibody found in approximately 30% of people with systemic lupus. Less than 1% of healthy people have this antibodymaking it helpful in confirming the diagnosis of systemic lupus.

What does dsDNA antibody mean?

Alternative Names: Description: Anti-(double-stranded)-DNA antibody is a highly specific marker for SLE and autoimmune (lupus) hepatitis. Elevated levels are found in 50-70% of active (especially untreated) SLE patients.

How accurate is the anti-dsDNA test?

Regardless of the assay used, anti-dsDNA antibody levels correlated with disease activity with r correlation coefficients ranging from 0.336 to 0.425 (p<0.0001).Conclusions: Assessing the diagnostic accuracy of anti-dsDNA antibody assays for SLE Comparable and potentially improvable, especially in specificity.
