PROBLEM TO BE SOLVED: To provide a treponema pollidum antibody measuring method which enables accurate measurement with high versatility and without causing non- specific reaction. ;SOLUTION: In this treponema pallidum antibody measuring method of detecting the degree of agglutination of the insoluble carrier as caused by an antigen/antibody reaction with a treponema pallidum antibody using an insoluble carrier supporting a treponema pallidum antigen to measure the treponema pallidum, 0.001-0.5mol. concentration of an aminoethane sulfonic acid derivative and/or aminopropane sulfonic acid derivative is added to a reaction system for agglutinating the insoluble carrier.;COPYRIGHT: (C)1997,JPO
