Interpretive Data
Positivity for anti-double stranded DNA (anti-dsDNA) IgG antibody is a diagnostic criterion of systemic lupus erythematosus (SLE). Specimens are initially screened by enzyme-linked immunosorbent test (ELISA). All ELISA results reported as "detected" (positive) are confirmed by a highly specific IFA titer (Crithidia luciliae indirect fluorescent test [CLIFT]). Some patients with early or inactive SLE may be positive for anti-dsDNA IgG by ELISA but negative by CLIFT. If the patient is negative by CLIFT but positive by ELISA and clinical suspicion remains, consider antinuclear antibody (ANA) testing by IFA. Additional information and recommendations for testing may be found at http://www.arupconsult.com/Topics/AutoimmuneDz/ConnectiveTissueDz/index.html.
Note
If dsDNA IgG antibody is detected, the result will be confirmed by Double-Stranded DNA (dsDNA) Antibody, IgG by IFA (using Crithidia luciliae). Additional charges apply.
