Clinical Significance
While the commonly used Anti-nuclear Antibody (ANA) test is a sensitive screening test for SLE and other connective tissue diseases, it is by no means specific for SLE. Because of this, all positive ANA homogeneous samples should be tested for specific antibodies to dsDNA. The presence of antibodies to dsDNA strongly indicates SLE; however, absence of these antibodies does not rule out SLE in all cases
