[The importance of C-reactive protein (CRP) in scarlet fever diagnosis (author's transl)].

Scarlet fever, especially in the mild and attenuated forms, proposes considerable diagnostic problems. The Authors, on the basis of their cases, remark the importance of C-reactive protein (CRP) positivity. After comparing the high initial positivity of this aspecific index of illness to the bacteriological pharyngeal findings and to the movement of antibodies against the Streptococcus, they think that CRP in scarlet fever may have a punctual significance, also for the ease and the quickness of this test.
