title: [Diagnosis of systemic lupus erythematosus (author's transl)].
abstract: The positive demonstration of ds-DNA in a particular concentration is a diagnostic criterium for systemic lupus erythematosus. The most commonly used test at present has the disadvantage that radioactively marked substances are required. Thus a test method was developed for the laser nephelometer which is simple and which detects the antigen-antibody complex directly. First measurements on sera from SLE patients showed a good correlation with radioimmuno assay.
