PURPOSE:To remove antigen-antibody composite materials, etc., and to permit definite measurement of a prescribed antibody at the time of measuring the antibody to acidic antigens by subjecting the antibody to a pretreatment with a basic material conjugated carrier. CONSTITUTION:Various kinds of extraneous antibodies and above all, antigen- antibody complex existing together with the antibody to be measured contained in a liquid sample or the like which is a specimen to be measured need be removed as far as possible in the case of measuring the antibody to the acidic antigens. The liquid sample is, thereupon, pretreated by the basic material conjugated carrier, for example, lysine-cephalose (commercially marketed). The antigen-antibody complex, etc., are removed by the pretreatment with such lysine-cephalose, by which the measurement of the antibody to be measured is executed purely in the form of having no disturbances. The definite measurement of an anti-ssDNA antibody and anti-CL antibody is thus permitted.
