<p>A measurement reagent for use in the measurement of C-reactive protein by a latex coagulation nephelometry method comprises particles each having, on the surface thereof, a group capable of reacting specifically with C-reactive protein. In a particle size distribution curve wherein the horizontal axis represents the particle diameter (x (nm)) of each of the particles and the vertical axis represents the frequency (y (%)) of the particles in terms of mass, at least one peak appears in a region in which x is less than 200 and at least one peak appears in a region in which x is equal to or more than 200, and the area bounded by a line connecting a coordinate point P1 (x1, y1) to a coordinate point V1 (x3, ymin), a line connecting the coordinate point V1 to a coordinate point V2 (x4, ymin), a line connecting the coordinate point V2 to a coordinate point P2 (x2, y2) and a line connecting the coordinate point P2 to the coordinate point P1 in the particle size distribution curve is 300 or more.</p> |
