As we need to develop at least some measure of pathogenicity of anti-dsDNA antibodies we propose that initial anti-dsDNA antibody screening is done by sensitive ELISA and supplemented by more stringent assays. Simultaneously the relevance of anti-dsDNA antibody presence needs to be restricted to clinical manifestations thought to be caused by anti-dsDNA antibody and within an appropriate time frame. Introduction After descriptions of organ involvement in patients with archetypal lupus erythematosus skin lesions and development of the concept of systemic lupus erythematosus SLE as a collagen vascular disease 1 2 a collaborative effort in the USA developed preliminary SLE classification criteria for interseries and epidemiologic evaluation. Retrospectively the cumulative presence of four or more criteria over a 7-year period correctly classified patients with 88 sensitivity and 95 specificity 3 . In 1982 the earlier autoimmune features lupus erythematosus cells or false positive test for syphilis were
