ABSTRACT:
An antibody is obtained by using as an antigen a complex of an antigen and the F(ab').sub.2 fragment of the human antibody of this antigen or an aggregate of the F(ab').sub.2 fragment of human immunoglobulin. This antibody reacts with an immune complex in a blood serum of a patient of systemic lupus erythematosus and with an immune complex in a blood serum of a patient of rheumatoid arthritis, and it does not react with an aggregated IgG. The amount of immune complex in a blood serum is easily and exactly determined by using this antibody.
