[C-reactive protein--determined by radial immunodiffusion and compared to the latex agglutination method].

C-reactive protein were assayed both with immunodiffusion and precipitation on latex C-reactive protein in 216 samples of sera from newborns with suspected septicemia. Both methods correlated well (r = 0.92) rendering the second one rather useful for early diagnosis of neonatal sepsis, since it produces results within a few minutes independent of complicated apparatus or trained personal.
