[C-reactive protein and blood picture parameters in the early diagnosis of infection in children with surgical diseases].

Since its detection fifty years ago, CRP is known as prototype of the acute-phase-proteines. It is a more sensitive, then specific indicator for bacterial infections. We found that CRP in accordance with clinical symptoms and the neutrophil-cell-index (I. S-ratio) makes a good prediction for early diagnosis of infections. Caution has to be payed in immediate post-operative phase, because the surgical trauma by itself can increase CRP-values.
