Interpretive Data

Positivity for anti-double stranded DNA (anti-dsDNA) IgG antibody is a diagnostic criterion of systemic lupus erythematosus (SLE). The presence of the anti-dsDNA IgG antibody is identified by IFA titer (Crithidia luciliae indirect fluorescent test [CLIFT]). CLIFT is highly specific for SLE with a sensitivity of 50-60 percent.

Some patients with early or inactive SLE may be positive for anti-dsDNA IgG by ELISA but negative by CLIFT. If the CLIFT result is negative but the patient has a positive ELISA and clinical suspicion remains, consider antinuclear antibody (ANA) testing by IFA. Additional information and recommendations for testing may be found at https://www.arupconsult.com/Topics/AutoimmuneDz/ConnectiveTissueDz/index.html.

No compliance statements are in use for this test.


Double Stranded DNA (dsDNA) antibodies (1:10 or greater) are found in 50-60 percent of systemic lupus erythematosus (SLE), 20-30 percent in Sjögren syndrome, 20-25 percent in mixed connective tissue disease (MCTD), and less than 5 percent in progressive systemic sclerosis (PSS). High titers of antibody to native (double stranded) DNA are specific for SLE.
