A comparison of passive haemagglutination test and immunofluorescent test for antibody to native deoxyribonucleic acid.
Antibody to double-stranded DNA is a specific marker for systemic lupus erythematosus. The recommended method for detection of this antibody is immunofluorescence. Haemagglutination was developed and the results of antibody detection were evaluated with those obtained by immunofluorescence. Human gr...
